摘要：
Disclosed is a voltage controlled oscillator including: a first element and a second element each passing a current therethrough varying based on a controlled signal; an oscillation circuit configured to generate an oscillation wave in each of a first state in which the current through the first element is current-inputted and a second state in which the current through the second element is current-inputted; a switching circuit switching between the first state and the second state; a current estimation circuit configured to estimate the current through the first element in the first state and to generate an estimation result; and a control circuit configured to generate the control signal for the second element so as to designate a current according to the estimation result as the current through the second element in the second state.
