156 Mbit/s preamplifier IC with wide dynamic rangefor ATM-PON application

Abstract
A 156 Mbit/s preamplifier IC has been fabricated for ATM-PON application with a new current-bypass circuit. A wide dynamic range of > 36 dB and small duty deviation at the large input signal was obtained with this preamplifier. The maximum output signal amplitude was reduced to < 350 mVpp. This reduction is helpful in designing a main amplifier with low supply voltage and dissipation power.
