Oscillation circuit and electronic device

Abstract

The oscillation circuit 1 comprises: an oscillator X1; a first capacitance CF having one end connected to the oscillator X1; a second capacitance CO having one end connected to the other end of the first capacitance CF; an output terminal Vo connected to a connection point N2 of the first capacitance CF and the second capacitance CO; an amplifier circuit A1 connected between a node between the oscillator X1 and the first capacitance CF and a connection point N2 of the first capacitance CF and the second capacitance CO to form an oscillation loop together with the first capacitance CF; a differential amplifier circuit A2 arranged on the oscillation loop; and a feedback path 3 configured to feed a part of an output on the output terminal Vo to the differential amplifier circuit A2.
