摘要： A low pass filter can be built in a chip by reducing the value of circuit element forming a low pass filter in a PLL circuit, especially by reducing the value of a electrostatic capacity. An active filter used in a PLL circuit having two charge pump circuits in a subsequent stage of a phase comparator includes a first circuit component connected between the output of one charge pump circuit and a ground, a second circuit component between the output of another charge pump circuit and the ground, and a voltage addition unit for adding up voltages between both ends of each of the first and second circuit components.

摘要： A prescaler that operates in a broad band. The prescaler includes a buffer and a counter. The buffer includes a first amplification circuit, which has three inverter circuits of different drive capacities, a second amplification circuit, which has four series-connected inverter circuits, and a feedback circuit. One of the inverter circuits is connected between a capacitor and an inverter circuit via a first switch circuit and a second switch circuit. This varies the drive capacity of the first amplification circuit. The feedback circuit functions as a variable resistor having two transistors.
