Abstract
A PLL circuit which comprises a phase comparator, a voltage-controlled oscillator whose oscillation frequency is controlled by an output from the phase comparator, a flip-flop circuit adapted to be set by an input signal, and a counter circuit responsive to an output condition of the flip-flop circuit to count an output from the voltage-controlled oscillator. The flip-flop circuit is adapted to be reset by an output from the counter circuit, and the phase comparator is adapted to receive an output from the flip-flop circuit and the output from the voltage-controlled oscillator.
