Abstract
A domino logic circuit includes a first evaluation unit, a second evaluation unit and an output unit. The first evaluation unit precharges a first dynamic node, discharges a footer node in a first phase of a clock signal, and evaluates a plurality of input signals to determine a logic level of the first dynamic node in a second phase of the clock signal. The second evaluation unit precharges a second dynamic node in the first phase of the clock signal, and determines a logic level of the second dynamic node in response to a logic level of the footer node in the second phase of the clock signal. The output unit provides an output signal having a logic level according to levels of a first voltage of the first dynamic node and a second voltage of the second dynamic node.
