A Partially Static High Frequency 18T Hybrid Topological Flip-Flop Design for Low Power Application

Also Available Domains Tanner EDA

Project Code :TVPGTO900


The main aim of this project is to design master slave flip-flop using adaptive coupling techniques with minimum number of transistors in order to reduce power consumption.


This paper presenting a different configuration of Flip-Flop with less number of transistor count. This structure depends on three configurations such as topological, logical and adaptive coupling techniques. This structure is designed using Complementary pass transistor logic. This novel design is simulated in cadence virtuoso employing GPDK library files.
