In this paper, the authors give a comparative analysis of an inductor-less Complementary Metal Oxide Semi-conductor (CMOS) single-ended current-mode Trans-Impedance Amplifier (TIA) intended for use in front-end optical communication for wideband operation. This paper uses N similar TIAs in parallel configuration to boost the overall bandwidth as well as the trans-impedance gain which is not possible with voltage-mode circuits. Using this method, the authors achieved the high bandwidth with high trans-impedance gain, with the minimum power consumption of 64.5 and 1.6mW for a 45nm and 180nm CMOS digital process respectively.
