Abstract:-This paper presents a new topology of Transimpedance amplifier using regulated
cascode (RGC) stage with series inductive peaking for the enhancement of overall bandwidth of
TIA and lowering the level of input referred noise current spectral density. TIA is able to achieve
low input impedance because of RGC stage. TIA also employs series inductive peaking techniques
for bandwidth enhancement by lowering the effect of junction capacitance of photodiode.
Simulated transimpedance gain is 67.2 dbΩ with -3db bandwidth of about 9.5 GHz. The simulated
input referred noise current spectral density is 10 pA/√Hz
Key Words:-Broadband, regulated cascade (RGC), bandwidth extension, transimpedance amplifier (TIA)
