Abstract
A fast voltage differential signaling (LVDS) transceiver ( ) having high repeater speeds up to 1.36 GBps, and also meeting the TIA/EIA-644 standard short-to-ground requirements. A mixed voltage-current mode differential driver has a respective control signal (A ) driving each of the drive transistors (Q ). The control signal (A ) is controlled by a transistor (M ) being a function of current through the respective drive transistor (Q ). A current mirror (Q , Q , Q ) is used to mirror current conducting through a transistor (Q ) in parallel with the drive transistor (Q ), which mirror current is compared against a current reference (Iref).
