摘要： A method for clock switching includes propagating a first clock signal through a first clock path, propagating a second clock signal through a second clock path, generating a first delay control signal based on the first clock signal, and generating a second delay control signal based on the second clock signal. The method also includes, in a first mode, coupling the first clock path to a delay circuit and inputting the first delay control signal to a control input of the delay circuit. The method also includes, in a second mode, coupling the second clock path to the delay circuit and inputting the second delay control signal to the control input of the delay circuit.
