ABSTRACT:
A correction circuit for controlling a correction required circuit includes an oscillator circuit, and a logic circuit which counts an oscillation frequency of the oscillator circuit and thus produces a control signal which causes the oscillator circuit to oscillate at a constant frequency. The control signal changes element values of elements of the oscillator circuit and the correction required circuit so that characteristics of the oscillator circuit and the correction required circuit can be controlled.
