A wide-band limiting amplifier for optical fiber repeaters

An integrated amplifier having a bandwidth of 470 MHz, and a gain and limiting range of 60 dB has been realized using a cascade of three cells on an uncommitted array. The circuit is capable of operating in optical fiber repeaters in the signal or retiming path at transmission rates up to 650 MBd. Direct expressions for calculating the gain and bandwidth have been derived which allow optimization of the component values, bias conditions, and transistor parameters for a chosen application.
