ABSTRACT:
A phase detector includes transistors that generate first and second phase error signals. The phase detector resets the first phase error signal in response to at least one of the first and the second phase error signals through a first reset path having a maximum reset delay that is equal to or less than a sum of switching delays of three transistors in the first reset path. The phase detector resets the second phase error signal in response to at least one of the first and the second phase error signals through a second reset path having a maximum reset delay that is equal to or less than a sum of switching delays of three transistors in the second reset path.
