Abstract
We present a transimpedance amplifier in the optical receiver front-end featuring with an integrated equalizer up to 45 Gb s−1. It integrates a Schottky-junction varactor diode at the input. The equalization in frequency-domain can be achieved by varying the applied voltage at the Schottky diode. For this end, the proposed circuit was fabricated and measured in both frequency and time-domain. By measuring S-parameters up to 45 GHz and eye-waveforms at 40 and 45 Gb s−1, the proposed circuit manifests its functionality as the transimpedance amplifier with an integrated analog equalizer.
