Patent ID: 7259608

Claim:
A method, comprising: propagating a first signal through a plurality of serially-coupled first delay elements responsive to a first transition of an input clock signal, each of the first delay elements providing a first delay; determining a first number of first delay elements of the plurality of first delay elements that the first signal has propagated through between the first transition of the input clock signal and a second transition of the input clock signal; propagating a second signal through the first number of a plurality of serially-coupled second delay elements, each of the second delay elements providing a second delay that is different from the first delay; propagating a third signal through the first number of a plurality of serially-coupled third delay elements, each of the third delay elements providing a third delay that is different from the first delay and the second delay; propagating a fourth signal through the first number of a plurality of serially-coupled fourth delay elements, each of the fourth delay elements providing a fourth delay that is different from the first delay, the second delay and the third delay; and propagating a fifth signal through the first number of a plurality of serially-coupled fifth delay elements, each of the fifth delay elements providing a fifth delay that is different from the first delay, the second delay, the third delay and the fourth delay.
