Abstract
In this paper we introduce a novel technique for achieving DC bias stabilisation of Heterojunction Bipolar Transistor (HBT) based distributed amplifiers whilst maintaining low frequency gain, without the use of large emitter decoupling capacitors. Equations are presented which show the underlying principles and limitations of the new technique. In addition, simulation results are given which demonstrate its effectiveness when compared to a frequently used conventional method
