Abstract
A current-controlled linear MOS earthed resistor that requires only three transistors is realised by means of a new linearisation technique. A nonlinearity within ±1.5% full scale in the 0-4 V voltage range for a 5 V supply is experimentally achieved with discrete MOS devices. However, much higher linearity can be expected if the ratio of two transistor sizes are chosen exactly, according to the derivation. A floating resistor, derived from the earthed one, is also presented
