Abstract
A phase signal select circuit includes a supporting path coupled to a tri-state inverter circuit. The supporting path reduces effects of hysteresis on signal transfer. An apparatus includes at least one input node responsive to a respective one of at least one input signal. The apparatus includes at least one circuit coupled to a respective one of the at least one input node and coupled to an output node. Individual ones of the at least one circuit are configured to provide a version of the respective input signal to the output node in response to a first state of a respective select signal. The apparatus includes at least one second circuit coupled to a respective one of the at least one circuit. The at least one second circuit is configured to toggle nodes of the at least one circuit in response to a second state of the respective select signal.
