摘要： A method for transferring power and information across an isolation barrier comprises transferring power across a power transfer isolation barrier between a primary circuit and a secondary circuit while maintaining isolation between the primary and secondary circuits, and transferring data between the powered system and the isolated system across a communication isolation barrier that is distinct from the power transfer isolation barrier.

摘要： A circuit for processing the control signal inputs for a control data signal decoder wherein a reference voltage and a reference current are generated for use in processing a stream of control signal bits. The control signal data stream is filtered, buffered and exponentialed. The processing serves to cancel out variations in temperature, resistance, process variations and circuit voltages to yield a stable control signal current.

摘要： A class-D pulse width modulated amplifier. The amplifier includes a current switch, an integrator and a comparator connected in a feedback loop. The feedback loop generates an ultrasonic frequency carrier which is utilized in the pulse width modulation of an audio input signal. In one embodiment a current switch and an audio input source are in electrical communication with an integrator. The output signal of the integrator is the input signal to a phase split differential output comparator having hysteresis. The differential output signals of the comparator are the input signals both to a load and to the current switch, thereby completing the feedback loop. In one embodiment the current switch includes compression circuitry.

摘要： A circuit capable of simulating a transistor or a semiconductor diode with controllably adjusted voltage characteristics contains a main transistor (Q0). An input voltage (V.sub.CS) to a control system (8) is amplified with a gain set by a pair of resistors (R1 and R2) to produce a control voltage (V.sub.C) for the transistor. This downscales the forward voltage characteristics of the circuit from those of the transistor. A floating power supply (10) in series with the control electrode of the transistor permits upscaling or further downscaling of the circuit voltage range.
