Abstract

This paper presents the analysis and design of a 2.5 Gbit/s transimpedance amplifier (TIA) realized in 130nm CMOS technology. The proposed TIA uses a common source (CS) amplifier with active inductive peaking (AP-TIA). The TIA is followed by a post amplifier and an output driver to provide an interface to the measurement setup. The post layout simulation demonstrates that the TIA achieves 46.16 dBΩ transimpedance gain with 2 GHz bandwidth for 2 pF input capacitance including the photodiode, ESD, and pad capacitance. The integrated input referred noise current is 1.062 μArms. The complete optical receiver has 76.78 dBΩ transimpedance gain, and optical sensitivity of -21 dBm for BER= 10-1 at data rate of 2.5 Gbit/s. The TIA alone consumes 5.4 mW whereas the total power consumption of the complete optical receiver is 47.3mW for 1.8V single supply voltage.
