Abstract
A GaAs FET monolithic integrated transimpedance preamplifier for 10 Gbit/s optical fibre transmission is realised using a newly developed capacitor peaking technique. A 3 dB bandwidth of 8.6 GHz and 19 dB gain is achieved in S-parameter measurements. A 3 dB bandwidth of 7 GHz and −12.0 dBm sensitivity at 10 Gbit/s are achieved in an optical front-end circuit with a GaInAs pin photodiode
