Abstract

A bus transceiver having a driver with charging/discharging characteristics that are device-independent and a receiver that provides adequate noise immunity is described. The transceiver uses a reference network to modulate the conductance of a depletion device as a function of device parameter variations in order to maintain a constant response time for the driver and optimize peak current. The receiver uses a modified differential amplifier to provide high gain and hysteresis sufficient for a desired level of noise immunity.
