Classification: CPC G  H | IPC G  H

Claim 2:
3. The signal detection circuit according to claim 1, further comprising:
a third capacitor having a first terminal connected with another main terminal of the switching element, the main terminal of the switching element corresponding to a first main terminal and another main terminal of the switching element corresponding to a second main terminal; and
a fourth capacitor having a first terminal connected with a predetermined reference potential,
wherein
the detection circuit has a differential configuration,
the detection receives, as the input signals, the signal output from the second terminal of the first capacitor, the signal output from the second terminal of the second capacitor, a signal output from a second terminal of the third capacitor, and a signal output from a second terminal of the fourth capacitor, and
the detection circuit detects the detection target signal based on the input signals.
