Abstract :
We propose a stable two-port amplifier concept using resonance phase transistors (RPT). While an RPT is a highly unstable device, the cascode of two RPT allows us to realize stable two-port amplifiers. The RPT cascode circuit shows an increase of the maximum stable gain GMSG by 21 dB compared with an RPT in common emitter configuration. To minimize parasitics a very compact realization topology is given.
