Abstract
A phase detector includes a phase propagator circuit including a plurality of flip-flops. Each flip-flop includes a clock input configured to receive a clock signal having a different phase relative to phases of the clock signal received by other flip-flops in the plurality of flip-flops. The phase detector further includes a phase controller coupled to the clock input of each flip-flop in the plurality of flip-flops. The phase controller is configured to provide the different phases of the clock signal to the plurality of flip-flops such that the different phases are scaled exponentially relative to one another.
