ABSTRACT:
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.
