Common anode amplifier of a commercial MOS transistor in avalanche gated diode configuration

Abstract

In this paper we present a voltage amplifier using a gated diode in breakdown regime. The diode is biased with a constant current and is in common anode configuration. The measured diode was obtained from a commercial nMOS transistor that has the substrate pin available. The circuit will be analyzed in this paper and the theory is in good agreement with the measurements.
