Abstract:
A generator of synchronization pulses intended for at least two registers, including a first input intended to receive a clock signal and at least one output intended to deliver the pulses on the clock input of said registers, and at least one second input intended to receive a signal for forcing the output, independently from the clock signal, to make said registers transparent.
Abstract:
A testable, prechargeable circuit has a driving circuit for producing a driving circuit output signal. A timing circuit receives a clock signal and the driving circuit output signal to cause an output of the testable, prechargeable circuit to be in a low state when the clock signal is low. The timing circuit also causes the output of the circuit to be timed with a state change in the clock signal to provide a domino logic output signal. Either a data signal or a test signal are multiplexed to the input of the driving circuit to produce respectively the domino logic output signal or a test output signal. A static logic circuit receives the test output signal to produce a test signal output.
Abstract:
A cell library for designing integrated domino circuits has a first library portion with a plurality of selectable logic circuits having different transistor sizes and/or logic functions for selection according to desired logic function and parametric characteristics. A second library portion includes a plurality of selectable prechargeable driver circuits. Each of the driver circuits is configured to be connectable to an output of a selected one of the logic circuits. The driver circuits also have at least different transistor sizes. Standard FET devices may be constructed to precharge the output node of the selected logic circuit in the design of a domino logic circuit.

Abstract:
A push-pull pulse register circuit. The push-pull pulse register circuit includes a first logic inverter having first-inverter input and first-inverter output, a second logic inverter having second-inverter input and second-inverter output, a third logic inverter having third-inverter input and third-inverter output and configured to receive logic input data at the third-inverter input, a first logic gate having first-gate input, first-gate output, and first-gate control input, and a second logic gate having second-gate input, second-gate output, and second-gate control input. The third-inverter input is coupled to the first-gate input; the third-inverter output is coupled to the second-gate input; the second-inverter input is coupled to the second-gate output and the first-inverter output; the second-inverter output is coupled to the first-gate output and the first-inverter input; the first-gate control input is coupled to the second-gate control input; and the first-gate and the second-gate control inputs are configured to receive a clock pulse.
