A logic gate circuit and related methods and apparatus exhibit reduced voltage swing and thereby consume less power. The circuit is connected to a plurality of input signals and a clock signal. The circuit produces an output. The circuit comprises a node, a pull-down network and an N-type MOS transistor. The pull-down network is connected to the node, a first reference voltage, the plurality of inputs and the clock signal. The N-type MOS transistor is connected between the node and a second reference voltage. The N-type MOS transistor is also connected to a complement of the clock signal. A method of the invention accepts a complement of a clock signal and pre-charges a node to a voltage less than a power supply voltage, in response to the complement of the clock signal. The method also accepts a plurality of input signals and accepts the clock signal. The method conditionally discharges the node, in response to the clock signal, on the basis of the plurality of input signals.
