WIPO Patent Application WO/2021/075247
Kind Code:
A1
Abstract:
[Problem] To provide an electronic circuit capable of quickly stabilizing output voltage. [Solution] This electronic circuit comprises: a filter circuit connected to a bias power supply via a first signal line and having a first resistor; a first switch connected in parallel to the first resistor; an amplification circuit connected to the filter circuit via a second signal line; a feedback circuit connected between the output side of the amplification circuit and a second terminal; and a control unit configured so as to control the first switch on the basis of signals supplied from the filter circuit and short-circuit the first resistor.
