Abstract:
A phase locked loop (PLL) includes a first charge pump coupled to a filter. The first charge pump may feed the filter a first current. A second charge pump is coupled to the filter. The second charge pump may feed the filter a second current. A first gate is coupled to an input of the second charge pump. The first gate selectively gates the second current.
