A low-power DC-to-27-GHz transimpedance amplifier in 0.13-µm CMOS using inductive-peaking and current-reuse techniques

The growing demand for high-speed communication necessitates high-data-rate and power-efficient integrated optical link solutions. In this paper, a power-efficient CMOS transimpedance amplifier (TIA) is proposed which uses current-reuse and inductive-peaking techniques to achieve a wide bandwidth, a low input impedance, and a high gain. As a proof-of-concept, a DC-to-27-GHz TIA is designed and laid out in a 0.13-μm CMOS process. Post-layout simulation results show that in the presence of a photo diode with a capacitance as large as 500 fF, the TIA achieves a 3-dB bandwidth of 27.3 GHz and a gain of 50 dBΩ while consuming 14.3 mW from a 1.2-V supply.
