An oscillator circuit includes: an arithmetic section configured to correct a first input code value and thereby generate a first code value that is within a first predetermined range, the arithmetic section being configured to correct a second input code value in correspondence with a correction amount of the first input code value and thereby generate a second code value, and the first predetermined range being narrower than a range of the first input code value; and an oscillation section configured to generate an oscillation signal having a frequency that varies at first sensitivity based on the first code value and varies at second sensitivity based on the second code value, the second sensitivity being higher than the first sensitivity.
