A 156 Mbit/s preamplifier IC has been fabricated for ATM-PON applicati
on with a new current-bypass circuit. A wide dynamic range of > 36dB a
nd small duty deviation at the large input signal was obtained with th
is preamplifier. The maximum output signal amplitude was reduced to <3
50mV(pp). This reduction is helpful in designing a main amplifier with
low supply voltage and dissipation power.
