PROBLEM TO BE SOLVED: To provide a PLL circuit which prevents the occurrence of a phase offset and reduces an operation voltage. SOLUTION: A phase control part 21 of the PLL circuit where a charge pump part is divided into two of an integrating part 20 and the phase control part 21 outputs differential outputs, and two outputs are connected by a resistance element R to eliminate a bias difference, and thus a stable low-voltage operation is realized. |
