Abstract :
It is shown that, with the aid of five system blocks (namely two differentiators, an integrator, a multiplier and a nonlinear transresistor) it is possible to obtain an inherently linear transresistor. A circuit implementation that comprises only two capacitors and a handful of transistors is proposed. The transresistor can be linearly controlled over a wide range, from a few kilo-ohms up to many giga-ohms
