摘要： A static ternary gate is disclosed. The static ternary gate includes a drain-ground path configured to output a drain voltage through a first transistor when a first pull-up circuit is turned on, and output a ground voltage through a second transistor when a first pull-down circuit is turned on, a half-drain path configured to output a half-drain voltage through the first transistor and the second transistor when both a second pull-up circuit and a second pull-down circuit are turned on. The first transistor is configured to connect a node between the first pull-up circuit and the second pull-down circuit to an output terminal, and the second transistor is configured to connect a node between the second pull-up circuit and the first pull-down circuit to the output terminal.
