This paper describes a broadband differential regulated cascode (RGC) transimpedance amplifier (TIA) designed in 130-nm SiGe process. Cross-coupled structure and two common emitter (CE) stages feedback loop are employed to reduce input impedance. The simulation results show that the proposed TIA has 46.35-dB \Omega differential transimpedance gain and 35.6-GHz bandwidth (BW). Overall, it achieves a clear 100-Gb/s PAM4 eye diagram. The total power consumption is 84mW.
