Abstract

In this paper we present a stable amplifier topology for resonance phase transistors (RPT). The RPT is an enhanced heterojunction bipolar transistor (HBT), having a positive gain far beyond its transit frequency fT. However, due to its resonant character, the RPT is a potentially instable device, and therefore does not allow to realize stable amplifiers in a straightforward design. The use of the cascode topology shows a considerable improvement of the stability and increases the maximum stable gain by 21 dB.
