Abstract
The charge pump circuit of a phase locked loop has a sensing device, latch and charge pump. When there are contemporaneous up and down signals being produced by the charge pump, a reset signal is provided from the sensing device to a latch which is coupled between the input to the circuit and the pump. Input signals are then inhibited from reaching the charge pump.
