ABSTRACT:
A voltage controlled current source outputs oscillator drive current and oscillator equivalent current. A signal oscillator outputs first source oscillation signal and second source oscillation signal. A differential amplifier outputs first amplification oscillation signal and second amplification oscillation signal. First switch circuit and second switch circuit output first current oscillation signal and second current oscillation signal, respectively. A first current value converter-amplifier circuit converts a value of the first current oscillation signal whereas a second current value converter-amplifier circuit converts a value of the second current oscillation signal, so that the thus converted values become output current finally. An adder outputs to the differential amplifier a differential amplifier drive current in which equivalent current for use with conversion is added up with the oscillator equivalent current outputted from the voltage controlled current source.
