摘要：In general, in one aspect, the disclosure describes a phase-locked loop circuit. The circuit includes an oscillator having a first control input and a second control input, wherein the first control input and the second control input act to control output frequency of the oscillator. The circuit further includes a first charge pump and a second charge pump. A first bias generator is coupled to the first control input of the oscillator and can receive electrical input from the first charge pump and the second charge pump. A second bias generator is coupled to the second control input of the oscillator and can receive electrical input from the second charge pump and the first bias generator.
