Abstract
A PLL including a phase comparator, a VCO, and a charge pump further includes a reset circuit. The reset circuit detects whether both of the charge pump transistors are in an ON state, and if so, generates a reset signal which inhibits the UP and DOWN signals generated by the phase comparator. The reset circuit includes first and second detection circuits and a signal generating circuit.
