Abstract:
1. An apparatus comprising: a phase detection circuit having first and second inputs, and first and second outputs, the phase detection circuit being configured to receive first and second input signals at the first and second inputs, respectively, wherein the phase detection circuit is configured to detect a phase difference between the first and second input signals and to indicate the detection of the phase difference with first and second output signals at the first and second outputs, respectively; and a balancer independent of the phase detection circuit, the balancer having at least one input receiving at least one of the first or the second input signal, wherein the balancer is configured to electrically couple the outputs of the phase detection circuit to each other directly in response to the at least one of the first or the second input signal such that the voltage levels of the output signals of the phase detection circuit are substantially equalized.
