A fast acting charge pump is provided which is suitable for use in a locked loop circuit where very short duration first and second adjustment pulses are produced by a phase detector. The first complement of the second adjustment pulses are used to switch the output of the charge pump through respective pairs of switching and associated biasing transistors, while a complement of the first and second adjustment pulses are respectively capacitively coupled to interconnection nodes of the pairs of switching and biasing transistors.
