Abstract
A voltage-to-current converter in MOS technology includes a signal resistor formed by a channel of a MOS signal transistor (11, 12, 13, 14) with a source electrode and a drain electrode which form terminals of the channel. A gate electrode is provided for connecting a gate voltage (V.sub.g) for adjusting the resistance of the channel and a bulk electrode is provided for connecting a bulk voltage (V.sub.b), and a supply is provided for supplying source, drain, gate and bulk voltages to the electrodes, for non-saturated operation of the signal transistor. The supply includes control circuitry (30) for controlling the bulk voltage in response to the gate voltage. Consequently, the third-order distortion of the voltage-to-current converter is reduced.
