Abstract:
1. An optical receiver comprising: a first photo-detector to receive a first optical signal and to generate a first current signal; a first transimpedance amplifier circuit to convert the first current signal to a first differential voltage signal, wherein the first transimpedance amplifier circuit is configured to produce a differential voltage and is further configured to difference the components of the differential voltage to produce said first differential voltage signal wherein the first transimpedance amplifier comprises three stage pairs, where each pair comprises two inverter amplifiers, and where the two inverter amplifiers of the second stage pair are resistively cross coupled; a clock recovery circuit having a phase interpolator to generate an aligned clock signal for said first differential voltage signal; a sampler circuit to receive the aligned clock signal and to receive the differential voltage signal and to generate a digital voltage sequence; and a deserializer circuit to receive the digital voltage sequence and to generate an N-bit data.
