Abstract
Provided is a detector circuit that includes: a first transistor that has an alternating current signal input to a base thereof, and that outputs a first detection signal that depends on the alternating current signal from a collector thereof; a second transistor that has the first detection signal input to a base thereof, and that outputs a second detection signal that depends on the first detection signal from a collector thereof; and an alternating current signal path along which the alternating current signal is supplied to the base of the second transistor.
Claims17
A detector circuit comprising:
- a first transistor, wherein an alternating current signal is input to a base of the first transistor, and a first detection signal that depends on the alternating current signal is output from a collector of the first transistor;
- a second transistor, wherein the first detection signal is input to a base of the second transistor, and a second detection signal that depends on the first detection signal is output from a collector of the second transistor;
- and
- an alternating current signal path along which the alternating current signal is supplied to the base of the second transistor.
