ABSTRACT:
Embodiments of the present invention relate to a low voltage differential signal driver (LVDS) circuit which comprises a current source, logic controlled switches for controlling the driver's output, an electronic load circuit coupled across the circuit, and a common-mode resistor feedback circuit coupled across the circuit, in parallel with the RC load, for tuning the driver's impedance. The driver is enabled to operate without op-amps and achieves optimum performance at 1.8 v supply voltages.
