Patent ID: 7791378

Claim:
A phase detector comprising: a first input; a second input; first circuitry in communication with the first and second inputs, the first circuitry operative to provide an indication of a phase difference between a first signal supplied by the first input and a second signal supplied by the second input, wherein the first circuitry provides an incorrect indication of the phase difference, the incorrect indication of the phase difference including an effect of an aberration in one of the first and second signals; and second circuitry in communication with the first circuitry, the second circuitry operative to reduce the effect of the aberration and to provide a correct indication of the phase difference, wherein the first circuitry comprises a logic element that outputs a first reset signal and the second circuitry outputs a second reset signal such that the first reset signal and the second reset signal are operative to reset a first and a second flip-flop of the first circuitry, the first reset signal and the second reset signal being independent from one another.
