Abstract
A wave detector circuit includes: a first transistor having its base and collector connected together, the first transistor receiving an AC signal and a reference voltage at its base and collector; a second transistor having its base connected to the base of the first transistor through a resistor, the second transistor outputting a detected voltage at its collector; and a diode-connected temperature compensation transistor connected between ground potential and the base and the collector of the first transistor.
