Low Power Dynamic Logic Circuit Design Using Footed Diode Domino Logic

In recent electronic devices power saving has more importance than any other thing. Dynamic logic circuits are one of the basic power efficient circuits which come into picture when dealt with low power. Dynamic logic circuits operate mainly in two phases, namely Pre-charge and Evaluate phase. Domino logic circuits are more power efficient and cooperatively faster circuits which operate on the above two phases. For extremely low power applications footed diode domino logic is applied. This project mainly deals with design of Dynamic logic circuit design based on footed diode domino logic with reduction in power and leakage current. In this proposed circuit we put a diode on the foot of domino logic circuit which results in power reduction as compared to reported and conventional domino logic. We are using NMOS as a diode and due to this extra diode (NMOS), in pre-charge period leakage current reduce due to stacking effect. Approximately 32% of power is saved using footed diode domino logic.
