Analysis of Different Types of Domino Logic: A Review
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 12
Abstract
Power and area will remain the main constraints in the designing of VLSI circuits. Dynamic CMOS logic circuits are broadly designed for high performance circuits due to their high speed. Conversely, the demerit of dynamic logic style is its high noise sensitivity. The main cause of this is the sub-threshold leakage current flowing through the pull down network and with continuous technology scaling, this problem is getting more and more severe. Compared to static CMOS circuits which have larger capacitance and offers more delay , Dynamic circuits are used to reduce those parameters of design. In that area lot of work has been done to improve the noise immunity and to make more power efficient without sacrificing the speed of the dynamic circuits. Domino with keeper, Domino with footer and keeper, High speed domino logic, Conditional keeper domino logic and several other techniques have been employed to improve the performance of the domino logic. Simulations were done in cadence earlier in order to visualize the different types of domino logic at different technology nodes and power supply for comparison purpose
