Data Switching

A novel low power clock gated successive approximation register (SAR) is proposed. The new register is based on gating the clock signal when there is no data switching activity. It operates with fewer transistors and no redundant transitions which makes it suitable for low power applications. The proposed register consisting of 8 bits has been designed up to the layout level with 1 V power supply in 90 nm CMOS technology and has been simulated using SPECTRE. Simulation results have shown that the proposed register saves up to 75% of power consumption.

Simulation Results

In this paper, a novel low-power and high-speed pulse triggered scan flip-flop is presented, in which short circuit current is controlled. Switching activity is decreased to reduce the consumed power of the scan flip-flop. Also, the total number of transistors through the path from input to the output is reduced and so the delay of the proposed scan flip-flop is decreased. Simulation results show 12% and 29% reduction in power consumption and delay of the proposed scan flip-flop, respectively. The results are given by comparison of our work with other scan flip-flops at 50% data switching activity.
