Abstract
An improved dynamic frequency divider circuit is disclosed. A DC voltage generating circuit (10) generates a DC voltage (Vcon) having a level the same as a threshold voltage of an inverter. A voltage application circuit (41) supplies a voltage (Vcon) to one electrode of a capacitor through a high frequency signal component cut-off coil (8), and a high frequency signal component is superimposed on the provided DC voltage. Accordingly, an input signal of an inverter (1a) swings around the threshold voltage level as a center, so that the inverter (1a) can provide a signal having the duty cycle of 50% as an output. As a result, the dynamic frequency divider circuit can be prevented from malfunctioning.
