Conversion circuit and electronic circuit

Abstract

A conversion circuit is a conversion circuit that converts an input current into an output voltage, the conversion circuit including a first terminal that is an input unit for the input current; a second terminal that is ground, a third terminal that is an output unit for an output voltage, the third terminal being configured to supply a power supply voltage via a power supply resistor, a first resistor, one end of which is connected to the first terminal and the other end of which is connected to the third terminal, and a regulator configured to detect a difference between a voltage at the first terminal and a predetermined reference voltage, and, when the voltage at the first terminal is higher than the reference voltage, perform control of adjusting an amount of current flowing from the third terminal to the second terminal according to a magnitude of the difference, lowering a voltage of the third terminal, and maintaining the voltage at the first terminal at the reference voltage, in which a gain of the conversion circuit is determined by the first resistor.
