Abstract

After investigation of the possible HBT low frequency noise sources and their localization in order to extract a HBT low frequency noise model, the realisation and performances of a S band Voltage Controlled Oscillator (VCO) is reported. This VCO is fully integrated in MMIC technology, and is based on a push-push topology. The circuit is covering 280 MHz tuning range around a centre frequency of 2 GHz with a phase noise of –95 dBc/Hz at 10 KHz offset.

Abstract

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.
