  • Patent number: 10847385
    Abstract: A lead frame used to assemble a semiconductor device, such as a smart card, has a first major surface including exposed leads and a second major surface including a die receiving area and one or more connection pads surrounding the die receiving area. The connection pads enable electrical connection of an Integrated Circuit (IC) die to the exposed leads. A molding tape sized and shaped like the lead frame is adhered to and covers the second major surface of the lead frame. The molding tape has a die receiving area cut-out that exposes the die receiving area and the connection pads on the second major surface of the lead frame and forms a cavity for receiving an encapsulant. The cut-out has an elevated sidewall for retaining the encapsulant within the cavity.

  • Publication number: 20200366360
    Abstract: A wireless multiple antenna system (200) uses a multi-antenna subsystem (211) to generate a composite sample waveform by continuously sweeping a plurality of receive beams (RX1-RXM) during each SSB transmission in a plurality of transmit beams (TX1-TX64), generating a composite received signal strength metric value from a batch of samples collected over the plurality of receive beams to determine the presence of the SSB, and then jointly searching the composite sample waveform for an optimal receive beam and an SSB frequency of any detected SSB that are used by the UE (210) to perform a cell search which matches a transmit beam from the base station (201) to the optimal receive beam.

    Abstract: The embodiments described herein include amplifiers that are typically used in radio frequency (RF) applications. Specifically, the amplifiers described herein include one or more transient termination circuits coupled to transistor inputs. For example, the transient termination circuits can be configured to reduce the transient response for some signal energy at frequencies below a baseband frequency (fB) of signals being amplified while not similarly reducing the transient response for signal energy near a fundamental frequency (f0) of the signals being amplified.

  • Patent number: 10841016
    Abstract: An example apparatus that employs circuitry operating in response to digital clock signal circuitry. The apparatus includes first circuitry and second circuitry. The first circuitry produces a high-frequency digital clock signal characterized by a high frequency which carries radiative noise interference and by a modulated low-frequency digital clock signal characterized by a low frequency modulated by a first type of modulation. The second circuitry produces another low-frequency digital clock signal by combining a disparate modulation signal and a feedback signal derived from the other low-frequency digital clock signal, wherein the disparate modulation signal is characterized by modulating the feedback signal via a second type of modulation that is independent of the first type of modulation and by cancellation/blocking of the radiative noise interference manifested by the circuitry operating in response to the digital clock signal circuitry.

    Abstract: A digital-to-analog converter (DAC) is described having a digital input, an analogue output, and two capacitors. The DAC has a controller. The controller is configured to generate a switching sequence including at least two switch cycles dependent on the input value received on the digital input. If the input value corresponds to an odd number, in a first switch cycle during a switch cycle first phase, the controller switchably couples a reference voltage to a first terminal and a ground voltage to a second terminal of one of the two capacitors, and switchably couples a ground voltage to a first terminal and the reference voltage to a second terminal of the other of the two capacitors. During a switch cycle second phase, the controller switchably couples a ground voltage to the first terminal and the analogue output to the second terminal of both capacitors.

  • Patent number: 10839877
    Abstract: A protection module for an electronic circuit prevents unintended write operations by a master module to functional registers of a protected module. The protection module includes soft lock bits (SLBs) that indicate whether corresponding functional registers are locked and control logic that supports (i) a page select (PS) control parameter that indicates whether access by the master module is to the functional registers or the SLBs and (ii) a mode select (MS) control parameter that indicates whether access by the master module to the functional registers is in a normal access mode, in which each written-to functional register is left unlocked, or an auto-lock access mode, in which each just-written-to functional register is automatically locked by setting the corresponding SLB. The functional registers and the SLBs share addresses that can fit within a single address space that includes the control parameters.

  • Patent number: 10831578
    Abstract: A processing system, such as for an automobile, includes multiple processor cores, including an application core and a safety core, and a fault detection circuit in communication with the processor cores. The fault detection circuit includes a progress register for storing progress data of an application executed on the application core. The safety core, which executes a fault detection program, reads the progress data from the progress register, and generates an output based on the progress data and an expected behavior of the application. The safety core writes the output to a status register of the fault detection circuit. The fault detection circuit includes a controller that reads the status register and generates a fault signal when the output indicates there is a fault in the execution of the application. In response, the application core either recovers from the fault or runs in a safe mode.

  • Patent number: 10833540
    Abstract: In a wireless charging system, a power-transmitting node (TX) has a power transmitter for transmitting power wirelessly to a power-receiving node (RX), a sampling and sensing circuit, a processor, and a signal receiver for receiving signals from the RX. The processor detects the presence of a foreign object (FO) during a power-transfer session using Quality Factor (QF) values. Estimated QF parameters are determined via exponential curve fitting using peak values of a damped sinusoidal waveform generated by a resonant circuit. Then the estimated parameters in the exponential curve are used to calculate the QF, which provides a robust measurement result even in a noisy environment.

  • Patent number: 10825486
    Abstract: A power control system, method, and architecture are disclosed for a multi-bank memory which provides independent, concurrent memory access to at least one memory block in each memory bank by using observation circuits to monitor bus masters connected over bus master interface signals to an interconnect for memory access requests to the multi-bank memory and to provide notifications to a power control circuitry that a valid memory access request was issued by a bus master over the bus master interface, where the power control circuitry processes the notifications received from each observation circuit and generates therefrom power control signals that are provided directly to each memory block and to bypass the interconnect, thereby separately controlling a power state for each memory block with power-up control signals that arrive at each memory block at or before a memory access request sent over the interconnect.
