Abstract
A voltage-current conversion circuit includes a voltage-current conversion resistor connected to an input terminal, and a current mirror circuit which mirrors a current supplied from the voltage-current conversion resistor, wherein the current mirror circuit is constructed to include a depletion-type transistor whose source voltage is biased to be higher than the substrate voltage.
Claims5
A voltage-current conversion circuit configured to covert a voltage at an input terminal to a current and output the current from an output terminal, comprising:
- a voltage-current conversion resistor connected to the input terminal;
- and
- a current mirror circuit which mirrors a current supplied from the voltage-current conversion resistor,
- the current mirror circuit comprising a depletion-type transistor, a source voltage of which is biased higher than a substrate voltage of the depletion-type transistor.
