This paper presents a 44 Gbit/s Transimpedance Amplifier (TIA) with wide-dynamic range and high-linearity for optical receiver fabricated in 130 nm BiCMOS technology. The TIA has the features of 67dBΩ overall transimpedance gain, a bandwidth of 28GHz, 10pA/√Hz of Input Referred Noise Current Power Spectral Density (IRNCPSD), and a power consumption of 95mW from a 2.5V supply. The Total Harmonic Distortion (THD) is less than 5% for a differential input current up to 2.63mApp, when the static input current is 0.1mA.
