Nonlinear resistor circuit using capacitively-coupled multi-input MOSFETS

摘要

A nonlinear resistor circuit utilizes capacitively-coupled multi-input MOSFETs in order to enable integration thereof by a standard CMOS process, and which can realize two types of nonlinear resistance characteristics; i.e., A-type and V-type nonlinear resistance characteristics. The circuit includes a core circuit which comprises enhancement-type N-channel and P-channel MOSFETs with source terminals being connected with each other.
