OSCILLATION DETECTION CIRCUIT |
摘要 |
An oscillation detection circuit according to the present invention has a differential circuit by a bipolar transistor where oscillation output of an oscillation circuit is inputted; a capacitance element that is connected to an output terminal of this differential circuit and charges or discharges in response to potential of the output terminal; and a detection circuit that detects a desired oscillation state of an oscillation signal terminal based on potential of this capacitance element.
