Abstract
A differential signaling circuit and a control circuit. The differential signaling circuit includes a first positive driver and a first negative driver. The first negative driver has different impedance than the first positive driver. The first positive driver and the first negative driver together define a first current path between positive and negative power supply terminals. A first output is defined on the first current path intermediate the first positive driver and the first negative driver. The control circuit includes a first driver that drives a transmission line at a first output voltage, a feedback amplifier responsive to the first output voltage to generate a control signal and a metal oxide semiconductor (MOS) driver coupled to the first driver and responsive to the control signal to make impedance of the first driver equivalent to impedance of the transmission line.
