Abstract
A method includes phase-shifting an output signal of a phase lock loop (PLL) circuit by applying an injection current to an output of a charge pump of a the PLL circuit. A circuit includes: a first phase lock loop (PLL) circuit and a second PLL circuit referenced to a same clock; a phase detector circuit that detects a phase difference between an output signal of the first PLL circuit and an output signal of the second PLL circuit; and an adjustable current source that applies an injection current to at least one of the first PLL circuit and the second PLL circuit based on an output of the phase detector circuit.
