ABSTRACT:
A data transceiver includes a transmitter connected at one end of a data transmission line and a receiver connected at the other end of the data transmission line. At least some portions of the transceiver are formed in CMOS. A temperature compensation circuit is connected to selected components of the transceiver to correct for temperature-induced variations in currents through those components. The temperature compensation circuit includes a pair of transistors connected, respectively, in parallel conduction paths. The transistors have unequal emitter areas, and their gates are tied together. The current through the larger transistor varies directly with temperature, and this current is reflected in a current mirror transistor that is connected to the shorted gates of the transistor pair. Since in CMOS technology current varies inversely with temperature, the current through the mirror transistor provides temperature compensation for selected components of the transceiver.
