Abstract
A semiconductor device includes a voltage control and oscillation circuit oscillating at a frequency according to a first control voltage to output an oscillation signal, a frequency/voltage conversion circuit receiving the oscillation signal from the voltage control and oscillation circuit and converting a frequency of the oscillation signal into a voltage, a control voltage generation circuit generating a new second control voltage having a level between that of the voltage converted by the frequency/voltage conversion circuit and that of a second control voltage generated previously, and an analog integration circuit integrating the second control voltage to generate the first control voltage and outputting the first control voltage to the voltage control and oscillation circuit.
