Abstract
A receiver circuit includes: a constant current circuit to generate second paired current signals according to first paired current signals; a current splitter circuit to output third differential signals having amplitudes smaller than the second paired current signals, from a first and second output nodes; first and second load resistor elements connected between a DC voltage node and the first and second output nodes, respectively; a differential transimpedance amplifier circuit to output paired voltage signals according to the third paired current signals, from first and second output terminals; and a voltage regulator circuit to adjust a gate voltage of an FET connected between a power supply wire and the DC voltage node, so as to reduce at least a difference in respective average potentials of the first and second output nodes and the first and second output terminals.
