A 274µW, Inductor-less, Active RGC-Based Transimpedance Amplifier Operating at 5Gbps

In this paper, a transimpedance amplifier (TIA) for 5Gbps applications in 90nm CMOS technology is proposed. The proposed TIA is based on a regulated cascade (RGC) structure. This TIA is designed fully with transistor, which occupies small area on chip, and operates at 5Gbps by consuming only 274μW....

Description
Summary:In this paper, a transimpedance amplifier (TIA) for 5Gbps applications in 90nm CMOS technology is proposed. The proposed TIA is based on a regulated cascade (RGC) structure. This TIA is designed fully with transistor, which occupies small area on chip, and operates at 5Gbps by consuming only 274μW. Simulation results in HSPICE using 90nm CMOS technology parameters shows 40.9dBΩ transimpedance gain, 4GHz bandwidth and 835nA rms (13.2pA/√Hz) input referred noise using 1v supply voltage. Analysis and simulations indicate that the proposed TIA is suitable to work as a low-power building block in analog front ends.
