Abstract

This paper describes a self-biased MOS transistor circuit with the ground referenced output voltage equal to the threshold voltage V . The circuit employs a series connection of three transistors where the middle transistor is in linear operation and external transistors are in saturation. The circuit can be applied for V extraction of both n-channel and p-channel transistors. The range of currents for better measuring of V in each case is established by simulation.
