摘要
Designed RGC TIA circuit was simulated on the basis of 0.25 mu m CMOS process using HSPICE. Supply voltage is 2.5 V. Power consumption of whole circuit is 16mW. Mid-band transimpedance(TIA) gain of TIA is 60.1dB Omega and -3dB 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 2(31)-1 PRBS signal. We obtained period of 300ps, wide and clean eye-diagram. Output eye-diagram voltage amplitude of 100 mu A input current signal is equal to 90mVpp. A core size is 210 mu m x 60 mu m.
