Current generation circuit

Abstract

Provided is a current generation circuit including a first terminal to be connected to a first external circuit; a second terminal to be connected to a second external circuit; a first resistor in which a potential is generated by the first external circuit connected through the first terminal; a second resistor in which a potential is generated by the second external circuit connected through the second terminal; a first amplifier circuit including a first positive input terminal to which the potential generated in the first resistor is supplied, and a first negative input terminal to which the potential generated in the second resistor is supplied; and a first MOS transistor having a gate connected to an output terminal of the first amplifier circuit, a source connected to the first negative input terminal, and a drain connected to a first differential current terminal.

Dependencies are inferred from the claim text.
