Abstract
A signal-generating circuit includes a voltage-controlled oscillator that generates an oscillated signal; a first frequency divider that generates a first divided signal by dividing the oscillated signal; a second frequency divider that generates a second divided signal by dividing the divided signal; a phase comparator that receives as input the second divided signal and a reference signal and outputs two signals corresponding to a phase difference therebetween; a loop filter that extracts a low frequency signal between the two signals to be output to the voltage-controlled oscillator; a third frequency divider that generates a third divided signal by dividing the first divided signal; a first frequency converter that generates a first frequency converted signal by multiplying the oscillated signal by the third divided signal; and a first multiplier that generates a multiplied signal by multiplying the first frequency converted signal by a first multiplication number.
