Linear and nonlinear mutators derived from GIC-type configurations

A two-OA GIC-type configuration with linear and nonlinear elements is investigated and two-port relations are derived. These relations correspond, for the linear cases, to different types of scalors, mutators and generalized mutators. When nonlinear resistors are used, functional composition of characteristics is achieved, the two-ports obtained behaving as "nonlinear scalors and/or mutators"
