Abstract
An electronic circuit has an output node that outputs a DC signal indicating a temporal change rate of a voltage of a measurement target node, a first capacitor and a first resistor that are connected in series between the measurement target node and a first reference voltage node, a second capacitor that is connected between the output node and a second reference voltage node, a first switch that switches whether or not to short-circuit the first reference voltage node and the output node, and a rectifier circuit that flows a current to a connection node between the first capacitor and the first resistor from the output node, and cuts off a current to the output node from the connection node.
