摘要： Provided are a method and system for removing an offset direct current (DC) component from an input waveform. The method includes multiplying the input waveform with a demodulation waveform to produce a first differential current signal. An absolute value representation of the demodulation waveform is multiplied with a reference DC offset value to produce a second differential current signal. The first and second differential current signals are then differenced.

摘要： A transmitter portion and a receiver portion are implemented within various devices that communicate using low voltage swing pads communicatively coupled via a trace. The transmitter portion of one device generates a current signal that is pushed/pulled to a low voltage swing pad and is then passed across the trace to another low voltage swing pad. The transmitter portion includes a current driver that outputs the current signal to the low voltage swing pads, and the receiver portion includes a trans-impedance amplifier that transforms the received current signal into a voltage signal. The low voltage swing pad driver and receiver generates a relatively low voltage swing when compared to CMOS full-scale voltage swings thereby significantly reducing the possibility of introducing any noise and/or distortion of data that is communicated via the interface.
