Tunable transimpedance amplifiers with constant bandwidth for optical communications

In this paper, two adaptive transimpedance amplifiers (TIAs) for optical communication receivers are presented and compared. Both TIAs are realized in a low-cost digital 0.35 mum CMOS process and fed from a single 1.8 V voltage supply. A transimpedance variation range of more than 12 dBOmega is attained with an almost constant bandwidth of about 1 GHz. The proposed configurations are characterized by their low-power operation and low input-referred spectral noise.
