ABSTRACT:
A low-voltage differential signal driver for high-speed digital transmission includes a first converter operable to receive a signal in a first type and convert the signal into a second type, and a cascode current mirror coupled to the first converter. The cascode current mirror provides an impedance level that increases a differential output voltage.
