Abstract:
A static complementary transistor type logic gate circuit includes a plurality of input terminals for receiving a corresponding plurality of input signals, and an output terminal. The logic gate circuit further includes a first plurality of transistors of one conductivity type, arranged to form a plurality of pullup paths for selectively connecting the output terminal, through one or more intermediate nodes, to a positive supply voltage based on the plurality of input signals; and a second plurality of transistors of the complementary conductivity type, arranged to form a plurality of pulldown paths for selectively connecting the output terminal, through one or more intermediate nodes, to a negative supply voltage based on the plurality of input signals. A precharge device is configured to selectively charge an intermediate node to the far-side supply voltage when the intermediate node is disconnected from the near-side supply voltage and disconnected from the output terminal.
