Abstract
The invention discloses a charge pump, a phase locked loop circuit and a charge pump method. The charge pump comprises an input port, a switch and an output port. The input port receives a phase frequency adjustment parameter. The switch switches a first current on or off, according to the phase frequency adjustment parameter, and keeps a second current on. The first current is larger than the second current. The output port outputs a sum of the first current and the second current to a low pass filter.
