Abstract
In this paper, a 10-Gb/s, 95-dB�, 20-mW optical receiver front-end is realized in a 0.13-�� m CMOS technology for high speed serial interface. To guarantee 10-Gb/s operation using low cost photodiode, the effect of inherent photodiode parasitic capacitance should be suppressed. Thus, LC-ladder filter and modified common-gate amplifier is exploited as the input stage of pre amplifier. To enhance the bandwidth, capacitive degeneration, active feedback, and negative impedance compensation, and inversely scaling technique are exploited in pre and post amplifier.
