A Monolithic Multi-Stage 6-18 GHz Feedback Amplifier

A design approach and circuit modeling method, which includes parasitic effects, will be presented for a two-stage monolithic feedback amplifier with enhanced high frequency performance. Using the proposed approach, a 6-18 GHz amplifier has been demonstrated with low input/output VSWR, respectable noise figure (6 dB) and a minimum gain of 8 dB.
