چکیده:

In this work, the domino logic with the variable threshold voltage keeper which uses an efficient body bias is proposed. The generator which consists of a capacitor and a diode is based on the voltage doubler technique. In the proposed scheme, the keeper size may be increased to
improve the noise-immunity of the domino logic without significantly increasing the power and the delay. In addition, the proposed generator circuit is simple, consumes a smaller area, and operates with a single supply voltage. The results of simulation for a 0.18µm CMOS technology
shows an improvement of 18% and 59% in power and delay, respectively, for this technique compared to the standard domino logic.
