13th German Microwave Conference (GeMiC 2020), Cottbus, Germany, Mar. 09-11, ISBN 978-3-9820397-1-8, pp. 52-55 (2020).


This paper investigates noise modeling of transferred-substrate indium phosphide double heterobipolar transistors (InP DHBTs). It is shown that the shot noise of these devices exhibits a pronounced correlation which allows for a reliable extrapolation of the noise performance based on standard noise measurement at lower frequencies, or even on the knowledge of small-signal model parameters alone.
