発明の名称 (英語) PLL CIRCUIT, AND RADIO COMMUNICATION DEVICE EQUIPPED THEREWITH
発明の概要(英語) In an ADPLL circuit (100), a DCO gain estimation unit (20) estimates, on the basis of the gain of a digital control oscillator (10), which is estimated in the state in which the loop gain with some value is set for a loop filter (18), and the element parameter of the digital control oscillator (10), the gain of the digital control oscillator (10) in the state in which the loop gain with another value is set for the loop filter (18).
