An optical module includes an optical receiver with a complementary metal-oxide semiconductor (CMOS) transimpedance amplifier (TIA) and a digital signal processing (DSP) circuit. The DSP circuit is integrated with the CMOS TIA and facilitates adaptability of the CMOS TIA, and the CMOS TIA can adapt by using information provided by the DSP circuit.

A pre-driver circuit includes a differential input circuit to receive a differential-input voltage. A latch circuit can latch voltage levels of output-voltage signals at a differential output port of the pre-driver circuit. A pair of capacitors couple the differential input circuit to the latch circuit. The pre-driver circuit can enable peaking of the output-voltage signals for high-speed operation of the pre-driver circuit and a digital-to-analog converter (DAC)-driver circuit coupled to the pre-driver circuit.
