Project Code :TVPGTO364


The main objective of this work is to reduce the power and to increase the speed of the sense amplifier and the latch was designed with a glitch-free and contention-free. Thus proposed SAFF is a good choice for replacing master-slave flip-flop in digital systems


A Sense Amplifier based Flip Flop (SAFF) is suitable for low-power high-speed operation. With the employment of a new sense-amplifier stage as well as a new single-ended latch stage, the power and delay of the flip-flop is greatly reduced. The proposed SAFF can provide low voltage operation by adopting MTCMOS optimization. The proposed SAFF delay and the power are smaller than those of the existing Master Slave Flip Flop (MSFF). 

The power-delay-product of the proposed SAFF improves compared with the conventional SAFF and MSFF, respectively the area of the proposed flip-flop decrease, the proposed SAFF could provide robust operation even low power supply voltages. The proposed design is implemented in 45nm technology in Cadence Virtuoso. By using this technology we can get the required output by giving 1 LVT.
