Abstract
The oscillating unitgenerates a signal having a frequency of n*f, i.e., n times a target frequency f. The control voltage generation circuitcompares the phase difference between a divided signal of a signal generated in the oscillating unitand the reference signal, and outputs a DC control voltage according to the phase difference to the oscillating unit, thereby controlling an oscillation frequency. The divider circuitconverts a signal generated in the oscillating unitto the target frequency f, by dividing the aforementioned signal into n equal units. By setting the oscillation frequency of the oscillating unit at n times the target frequency, the inductance and the capacitors can be formed on a semiconductor integrated circuit board.
