Dual-rail transceiver with improved signal-to-noise ratio for differential high-speed links

摘要

A signal transceiver includes a signal transmitter driving a first differential link between a supply voltage of the signal transmitter and a fraction of the supply voltage, and driving a second differential link between the faction of the supply voltage and a reference ground. The signal transceiver also includes a signal receiver in which the first differential link is coupled to a gate node of an NMOS transistor and to a source node of a PMOS transistor; and the second differential link is coupled to a source node of the NMOS transistor and to a gate node of the PMOS transistor.
