Abstract :
For the first time, two-stage transimpedance amplifiers using n-type Si/SiGe-MODFETs have been fabricated in order to check the potential of this novel device generation for analogue designs. S-parameter measurements showed -3 dBΩ bandwidths of 1.8 GHz with a transimpedance gain of 56 dBΩ. Circuits with lower bandwidths reached values for transimpedances of up to 72 dBΩ
