Measurement and Simulation of Microwave Noise Transient of InP/InGaAs DHBT with Polyimide Passivattion

Measurement and simulation of microwave noise transient of InP/InGaAs DHBT with polyimide passivation is reported in this paper for the first time and is believed to contribute to the overall broadband shot noise. This work provides a better insight into the noise transient mechanism of InP HBTs due to polyimide passivation and can be used to improve the device and circuit reliability.
