A wideband current-reuse-RGC TIA circuit with low-power consumption

Abstract

This paper presents a new Gain-Adder (GA) circuit for Current-Reuse (CR)-RGC TIA. The proposed GA circuit employs one transistor alone to enhance bandwidth and decrease power consumption. The proposed CR-RGC TIA circuit is designed in a 65-nm CMOS technology. The simulation results confirmed that the proposed CR-RGC TIA circuit improves bandwidth by 83% and decreases the power consumption by 34% in comparison with the conventional one.
