  • Patent number: 7659918
    Abstract: The present invention provides methods and apparatus for adjusting the resonant frequency, scan velocity or other parameters of a pivotally functional surface such as an oscillating mirror used as the scanning engine of a laser printer or projection display. The selected parameter is adjusted by the application of tensional or compression stress to the torsional hinges of the mirror. According to one embodiment, the appropriate stress is generated by a slice of piezoelectric material bonded to the mirror device itself or to other portions of the support structure of the scanning engine.

  • Patent number: 7659754
    Abstract: A power switching circuit in CMOS technology has a power MOS transistor and a driver stage. The power MOS transistor is operated at a higher supply voltage in excess of its maximum allowable gate-source voltage; and the driver stage of the level shifter is operated at a lower supply voltage substantially lower than the supply voltage for the power MOS transistor. The driver stage includes a pair of driver MOS transistors coupled in series between a higher supply voltage rail and a reference potential rail, and at an interconnection node coupled to the gate of the power MOS transistor. The gates of the driver MOS transistors are AC-coupled to drive signals of mutually opposite phase; and the gates of the driver MOS transistors are each connected to the higher voltage supply rail through a respective parallel connection of a first resistor and a second resistor connected in series with a non-linear component.

  • Patent number: 7660150
    Abstract: A method is provided for writing to a memory cell having a read access circuit that is separate and isolatable from a write access circuit. The method comprises providing a logic state to be written to the memory cell onto a write bit line coupled to the memory cell through the write access circuit, changing a write word line that controls the write access circuit from a deactivated low voltage state to an activated high voltage state, and changing a read word line that controls the read access circuit from an activated low voltage state to a deactivated high voltage state, wherein the change in voltage on the read word line provides a voltage boost to the voltage on the write word line caused by the electrical coupling between the read word line and the write word line to provide write assist to the memory cell during a write operation.

  • Patent number: 7659741
    Abstract: An integrated circuit (70) having parallel scan paths (824-842, 924-942) includes a pair or pairs of scan distributor (800,900) and scan collector (844,944) circuits. The scan paths apply stimulus test data to functional circuits (702) on the integrated circuit and receive response test data from the functional circuits. A scan distributor circuit (800) receives serial test data from a peripheral bond pad (802) and distributes it to each parallel scan path. A scan collector circuit (844) collects test data from the parallel scan paths and applies it to a peripheral bond pad (866). This enables more parallel scan paths of shorter length to connect to the functional circuits. The scan distributor and collector circuits can be respectively connected in series to provide parallel connections to more parallel scan paths. Additionally multiplexer circuits (886,890) can selectively connect pairs of scan distributor and collector circuits together.

  • Publication number: 20100027298
    Abstract: A synchronous rectifier is switched in accordance with a primary switch transition and a reference signal representing current in a current storage device to which the synchronous rectifier is coupled. A current emulator provides a signal representing current in the current storage device as a volt-second product so that current stored in the current storage device while the primary switch is on is discharged by the synchronous rectifier. The use of a current emulator provides an inexpensive solution for controlling synchronous rectifier transitions without resorting to more expensive current sensing solutions that are commercially impracticable. Blanking intervals are provided for avoiding false transitions of the synchronous rectifier when the primary switch turns on and after the synchronous rectifier turns off. The disclosed system and method can be applied to flyback converters for a synchronous rectifier on the secondary side of a transformer, or the inductor of buck converters.

  • Patent number: 7657806
    Abstract: Scan distributor, collector, and controller circuitry connect to the functional inputs and outputs of core circuitry on integrated circuits to provide testing through those functional inputs and outputs. Multiplexer and demultiplexer circuits select between the scan circuitry and the functional inputs and outputs. The core circuitry can also be provided with built-in scan distributor, collector, and controller circuitry to avoid having to add it external of the core circuitry. With appropriately placed built-in scan distributor and collector circuits, connecting together the functional inputs and outputs of the core circuitry also connects together the scan distributor and collector circuitry in each core. This can provide a hierarchy of scan circuitry and reduce the need for separate test interconnects and multiplexers.

  • Patent number: 7655492
    Abstract: A method for forming a MEMS device is disclosed, where a final release step is performed just prior to a wafer bonding step to protect the MEMS device from contamination, physical contact, or other deleterious external events. Without additional changes to the MEMS structure between release and wafer bonding and singulation, except for an optional stiction treatment, the MEMS device is best protected and overall process flow is improved. The method is applicable to the production of any MEMS device and is particularly beneficial in the making of fragile micromirrors.
