CHAIN-RULE RESISTANCE - A NEW CIRCUIT PRINCIPLE FOR INHERENTLY LINEARULTRA-LOW-POWER ON-CHIP TRANSCONDUCTANCES OR TRANSRESISTANCES

It is shown that, with the aid of five system blocks: namely two diffe rentiators, an integrator, a multiplier and a nonlinear transresistor, it is possible to obtain an inherently linear transresistor. A circui t implementation that comprises only two capacitors and a handful of t ransistors is proposed. The transresistor can be linearly controlled o ver a wide range, from a few kilo-ohms up to many giga-ohms.
