ABSTRACT:
A voltage-to-current conversion circuit is disclosed which includes a MOS transistor of a source-grounded type having a gate connected to an input terminal, an output circuit producing an output current at an output terminal in response to a drain current of the transistor, and a control circuit maintaining the drain voltage of the transistor to such a value that has the transistor operates in a non-saturation (triode) region.
