摘要： In an input receiver circuit includes a signal input for receiving a signal input to a chip, a chip output for supplying a buffered signal to circuitry on the chip and a positive feedback circuit coupled between the chip output and the signal input. The positive feedback circuit might comprise a first inverter having an input coupled to the signal input, a second inverter having an input coupled to an output of the first inverter, wherein an output of the second inverter provides the chip output, and an inverting buffer having an input coupled to the output of the second inverter and an output coupled to the signal input.

摘要： A power converter within an integrated circuit (“IC”) for providing DC power to one or more function circuit, where the power converter has a transformer circuit for receiving an AC power signal and for supplying a transformed AC power signal. A converter circuit receives the transformed AC power signal and then converts the signal into a DC power signal supplied to one or more function circuit. The transformed AC power signal might either be stepped up or stepped down. The transformer circuit might comprise two coils, where a first coil is magnetically coupled to a second coil. The first coil is a first spiral and the second coil is a second spiral wherein an insulating material layer is disposed between the first spiral and the second spiral. The transformer circuit might include transformers connected in parallel or in series and may further be connected correspondingly to more than one converter circuit coupled in parallel. An IC comprising the power converter circuit can be integrated into a computer system.

摘要： An improved output driver for HSTL includes a bias control transistor to absorb current leaking through the base-collector capacitance of the drive transistor and maintain the base voltage on the drive transistor. The bias control transistor is biased by a series network coupled between a base of the bias control transistor and ground, which keeps the bias control transistor at a bias near its turn-on bias, with a feedback capacitor coupled between the output and the base of the bias control transistor to turn on the bias control transistor when the output rises.
