Abstract :
A simple common-collector full-monolithic preamplifier is developed using an advanced 3 ¿m Si-bipolar IC technology SICOS. The amplifier characteristics are a 650 MHz bandwidth and a 5.2 pA/¿(Hz) equivalent input noise current at a 3 k¿ transimpedance. Measured optical sensitivity of a front end consisting of the amplifier and a Ge-APD is ¿36.2 dBm for an error rate of 10¿9 at a 560 Mbit/s bit rate and 1.3 ¿m wavelength.
