Abstract
A bias current circuit controls an oscillator that generates an oscillation signal of a frequency corresponding to an input current. The circuit includes a part that detects fluctuation of a control current for variably controlling the frequency of the oscillation signal and a part that generates an input current in which a fluctuation component of the control current is canceled using a current for cancelling the detected fluctuation of the control current.
