  • Patent number: 10580722
    Abstract: Described herein is a technology or a method for fabricating a flip-chip on lead (FOL) semiconductor package. A lead frame includes an edge on surface that has a geometric shape that provides a radial and uniform distribution of electric fields. By placing the formed geometric shape along an active die of a semiconductor chip, the electric fields that are present in between the lead frame and the semiconductor chip are uniformly concentrated.

  • Patent number: 9692336
    Abstract: A motor controller architecture and method of operating the same. The motor controller asynchronously generates multiphase control signals for a multi-phase electric motor, relative to the estimation of various state parameters used in generating those control signals. Latency between the state estimation task and the control signal generation task is addressed by storing a timestamp with each input data sample from the sensors, and maintaining that timestamp with the output data from state estimation. Knowledge of the timestamp value allows the control task to update the state estimates to compensate for the time difference between the input data sample and the current sampling period.

  • Patent number: 9222969
    Abstract: Assessing open circuit and short circuit defect levels in circuits implemented in state of the art ICs is difficult when using conventional test circuits, which are designed to assess continuity and isolation performance of simple structures based on individual design rules. Including circuit blocks from ICs in test circuits provides a more accurate assessment of defect levels expected in ICs using the circuit blocks. Open circuit defect levels may be assessed using continuity chains formed by serially linking continuity paths in the circuit blocks. Short circuit defect levels may be assessed by using parallel isolation test structures formed by linking isolated conductive elements in parallel to buses. Forming isolation connections on a high metal level enables location of shorted elements using voltage contrast on partially deprocessed or partially fabricated test circuits.

  • Patent number: 8898528
    Abstract: A process and apparatus provide a JTAG TAP controller (302) to access a JTAG TAP domain (106) of a device using a reduced pin count, high speed DDR interface (202). The access is accomplished by combining the separate TDI and TMS signals from the TAP controller into a single signal and communicating the TDI and TMS signals of the single signal on the rising and falling edges of the TCK driving the DDR interface. The TAP domain may be coupled to the TAP controller in a point to point fashion or in an addressable bus fashion. The access to the TAP domain may be used for JTAG based device testing, debugging, programming, or other type of JTAG based operation.

  • Patent number: 8755877
    Abstract: A mobile system for analyzing ECG data includes an analog front end module coupled to a mobile consumer device. The analog front end module is configured to collect ECG data from one or more leads and is operable to convert the analog ECG data to digital ECG data. The mobile consumer device is coupled to receive the digital ECG data, and is configured to perform QRS detection using a filter whose cutoff frequency is adapted to noise level in real time. The ECG signal is amplified non-linearly and three windowed threshold signals (D, E, J) are derived. The cutoff frequency for the QRS detection is dynamically selected as a function of the threshold signals. A sample in the amplified signal is identified to be a heart beat point only when the sample value is equal to the first threshold signal and greater than the filtered threshold signal.

  • Patent number: 8732551
    Abstract: A memory validation manager reserves a block of time for exclusive accesses to a memory bank having lines of memory for which validation codes provide a degree of error detection and correction for each memory line. The memory validation manager reads, processes, and corrects at least some of the contents of each memory line based on indications of validity encountered for each memory line. New data is written in response to a validation code. Likewise, a valid field for each line can be updated and a new validation code written for a memory when the valid field indicates that a validation code has not yet been written for a memory line. The memory validation manager processes data read from a first memory line while either reading or writing to another memory line to minimize the latency of the process of scrubbing memory lines.

  • Publication number: 20120038331
    Abstract: Systems and devices for smooth light load operation in a DC/DC converter are presented. The disclosed systems and methods enable smooth discontinuous conduction mode (DCM)/continuous conduction mode (CCM) transition. The disclosed systems and methods of smooth light load operation in a DC/DC converter may also avoid the generation of sub-harmonics during light load operation. In an example embodiment, a rising ramp is used to control the ON time of the converter oscillator, while a falling ramp controls the OFF time. During DCM operation, the minimum value of the falling ramp is clamped. The clamping of the falling ramp ensures a substantially similar level of the error amplifier output in both CCM and DCM and avoids disturbances caused by a difference in the error amplifier outputs between the modes.

  • Publication number: 20110162082
    Abstract: An electronic circuit includes a more-secure processor having hardware based security for storing data. A less-secure processor eventually utilizes the data. By a data transfer request-response arrangement between the more-secure processor and the less-secure processor, the more-secure processor confers greater security of the data on the less-secure processor. A manufacturing process makes a handheld device having a storage space, a less-secure processor for executing modem software and a more-secure processor having a protected application and a secure storage. A manufacturing process involves generating a per-device private key and public key pair, storing the private key in a secure storage where it can be accessed by the protected application, combining the public key with the modem software to produce a combined software, signing the combined software; and storing the signed combined software into the storage space.

  • Publication number: 20100241724
    Abstract: This invention is a method of operating a system having multiple finite state machines and a controller controlling an operational state of each finite state machine. Upon selection by the controller of a changed operational state, each finite state machine determines if it supports the changed operational state. If the finite state machine supports the changed operational state, it enters the changed operational state. If the finite state machine does not support the changed operational state, it enters an offline state. The controller may also determine whether a changed operational state is supported by each finite state machine.

  • Patent number: 7675272
    Abstract: In a method and system for regulating an output voltage, a linear voltage regulator (LVR) includes an adjustable shunt regulator (ASR) having a limited gain, a feedback circuit (FC), and a compensation resistor (CR). The limited gain causes the output voltage of the ASR to change in response to a change in an input current of the ASR. The FC generates a feedback voltage reference in proportion to the output voltage, the feedback voltage reference being provided to the ASR to control the output voltage. The CR is coupled to the ASR and the FC. The input current flows through the CR to provide a compensating voltage across the CR. The compensating voltage is provided to the feedback circuit to compensate the limited gain, thereby providing the output voltage that is substantially independent of the input current.

  • Patent number: 7404129
    Abstract: In a first embodiment a TAP of IEEE standard 1149.1 is allowed to commandeer control from a WSP of IEEE standard P1500 such that the P1500 architecture, normally controlled by the WSP, is rendered controllable by the TAP. In a second embodiment (1) the TAP and WSP based architectures are merged together such that the sharing of the previously described architectural elements are possible, and (2) the TAP and WSP test interfaces are merged into a single optimized test interface that is operable to perform all operations of each separate test interface. One approach provides for the TAP to maintain access and control of the TAP instruction register, but provides for a selected data register to be accessed and controlled by either the TAP+ATC or by the discrete CaptureDR, UpdateDR, TransferDR, ShiftDR, and ClockDR WSP data register control signals.
