Abstract

In this paper, a 10-Gb/s limiting amplifier (LA) was implemented in 0.18 mum CMOS. Modified active inductors and active feedback topology are employed to eliminate the trade-off among circuit bandwidth, power dissipation, and layout area, which is suitable for low cost applications. Based on the measurement results, the realized LA can operate up to 12-Gb/s with a 125 mV_pp single-ended output through equivalent 25-Omega load. The input dynamic range is 40 dB corresponding to the signal level range from 4 mV to 400 mV. The RMS jitter of the output signal is 2 ps and the total power dissipation (including output buffer) is only 60 mW under a supply of 1.8 V.
