摘要

A fully integrated 25 Gb/s low-noise optical receiver is presented which integrates transimpedance amplifier (TIA), continuous-time linear equalizer (CTLE), high-gain and highbandwidth limiting amplifier (LA), and clock and data recovery (CDR) circuit into a single die. The TIA employs an inverter-based pseudo-differential TIA scheme with input seriesinductor peaking, cross-coupled negative Gm pai...
