A fully differential CMOS limiting amplifier with active inductor for optical receiver

A fully differential CMOS limiting amplifier with low voltage drop active inductors and inversely scaled amplifier stages for bandwidth enhancement is presented in this paper. The amplifier is designed in a TSMC 0.18 /spl mu/m CMOS technology and SpectreS simulations shows a bandwidth of 1.8 GHz, a differential gain of 44 dB, and a power dissipation of 3.7 mW from 1 V power supply.
