Abstract
A novel current-mode transimpedance amplifier (TIA) architecture is proposed for optical receivers. This new architecture, based around the use of a uniquely biased common-base current buffer stage, allows stable, DC coupled TIAs to be designed in bipolar or CMOS processes operating from extremely low supply voltages and using very low levels of power. Noise performance is comparable to that of higher power designs that operate from higher supply rails. Simulation results have been obtained for a 47GHz fT SiGe BiCMOS process and also 0.25μm CMOS.
