Abstract :
A wideband AGC amplifier is monolithically integrated using an advanced Si-bipolar IC technology, SICOS. The fabricated IC exhibits an 8·4 dB maximum gain, 17 dB variable gain and 1·1 GHz bandwidth. It is shown that the SICOS technology is feasible for developing an equalising amplifier with a 37 dB gain and 700 MHz bandwidth for 400 Mbit/s optical repeaters.
