ABSTRACT:
An oscillator circuit includes a first terminal, a second terminal, a resonator that is connected to the first terminal and the second terminal, a first capacitor that is connected to the first terminal and a ground line supplying the ground electric potential, a second capacitor that is connected to the second terminal and the ground line, m inverters, where m is an odd number equal to or larger than three, which are connected in series between the first terminal and the second terminal, and a third capacitor that is connected to an input terminal of the n-th (where n is an integer satisfying 1≦n<m) inverter, counted from an input side of the inverter array and an output terminal of the (n+1)-th inverter.
