Abstract

Designed RGC TIA circuit was simulated on the basis of 0.25 mum CMOS process using HSPICE. Supply voltage is 2.5 V. Power consumption of the whole circuit is 16 mW. Mid-band transimpedance (TIA) gain of TIA is 60.1 dBOmega and -3 dB bandwidth is satisfied with photodiode capacitance and the average noise current spectral density of 18.9 pA/sqrt(Hz). TIA output eye-diagram of 2.5-Gb/s 2³¹-1 PRBS signal. We obtained period of 300 ps, wide and clean eye-diagram. Output eye-diagram voltage amplitude of 100 muA input current signal is equal to 90 mVpp. A core size is 210 mum times 60 mum.
