Abstract
An electronic circuit includes an output node configured to output a DC signal indicating a rate of change over time of voltage at a measurement target node. The rate-of-voltage change detection circuit includes a first capacitor and a first resistor connected in series between the measurement target node and a reference voltage node, a first rectifier circuit connected between the output node and a connection node of the first capacitor and the first resistor, and a second capacitor connected between the output node and the reference voltage node.
