Abstract
In an ADPLL circuit, on the basis of a gain of a digitally controlled oscillator estimated when a loop gain of a certain value is set in the loop filter and on the basis of a device parameter of the digitally controlled oscillator, the DCO gain estimation unit estimates a gain of the digitally controlled oscillator when a loop gain of another value is set in the loop filter.
