An ultra-compact 0.36 mm2 differential wideband amplifier fabricated using SiGe technology is presented. Measurements show an on-wafer gain of 20.8 dB and a 3 dB cutoff frequency of 32.0 GHz. The mounted amplifier's gain is 19.5 dB. The circuit is intended to operate as a predriver in a 40 Gbit/s fibre-optic communication system.
