Abstract :
In this paper, a fully differential CMOS limiting amplifier is presented for OC-48 SONET applications. With negative resistance and capacitance characteristics, it achieves significant gain and bandwidth enhancement. The amplifier was implemented in a 0.18-mum CMOS process, occupying the chip area of 0.025 mm2. Post-layout simulation results demonstrate the bandwidth of 2.4-GHz, the differential gain of 41-dB, the input sensitivity of 1.5 mVpp, and the power consumption of only 5.2 mW from a single 1.2-V power supply.
