ABSTRACT:
A data bus transceiver reduces self-induced noise by using trapezoidal drive waveforms. A differential receiver stage of the transceiver has a threshold voltage matched to the midpoint voltage of the drive waveform to reduce distortion, and a low-pass filter matched to the slew rate of the drive waveform to reduce noise while causing minimum progation delay. The transceiver has been integrated using back-to-back junction capacitors in the driver and filter circuits and these capacitors have been biased to reduce their variation in capacitance as a function of the voltage applied across them.
