Abstract
This paper proposes a novel and compact model for the avalanche noise diode which can be exploited in advanced Computer Aided Design (CAD) tools. The proposed model allows to concurrently simulate the diode behavior both from the impedance and the Excess Noise Ratio (ENR) point of view. It also allows to simulate the diode in its ON or OFF state. It was developed on Advanced Design System (ADS) of Keysight Technologies and verified against published measurements. The modelled input impedance is within the 15% of the measured one, in all the considered bandwidth. Moreover the modelled ENR compared to the measured one shows a variance within ±0.6 dB. The presented model can be employed in the design of calibration circuits of microwave radiometers, radio astronomy receivers and high reliability wireless systems. The application of the model in a use case design scenario is provided.
