چکیده

In this paper, a novel low power pulsed flip-flop (PFF) using self-controllable pass transistor logic is presented. The pulse generation logic comprising of two transistor AND gate is used in the critical path of the design for improved speed and reduced complexity. In the D to Q path inverter is removed and the transistor is replaced with pass transistor logic. The pass transistor is driven by generated clock pulse is used directly to drive the flip flop output. The presented design is compared with the SCCER and low-power pulse triggered flip-flop with conditional pulse enhancement (LPFFCE) scheme. As compared to the SCCER, LPFF-CE the proposed pulsed flip-flop (PFF) design features best speed, power. The proposed technique is implemented using TSPICE CMOS 180nm technology. The average power consumption for proposed design is reduced compared with the conventional flip flops. Keywords— Low power, pulsed flip-flop, pass transistor logic, critical path, self-controllable, power.

Designing a Novel Power Efficient D- Flip-Flop using Forced Stack Technique

In Integrated circuits a gargantuan portion of on chip power is expended by clocking systems, which comprises of timing elements such as flip-flops, latches and clock distribution network. These elements absorb approximately 30% to 60% of the total power dissipation in the system. In order to design high performance and power efficient circuits a scrupulous approach should be adopted to reduce ...

Performance Improved Low Power D-Flip Flop with Pass Transistor Design and its Comparative Study

Power reduction and speed are the two major concerns in a VLSI design. To achieve better performance in terms of power, different transistor structures are used. Now a day, the MOS devices are wide spread, because they consume less power compared with bipolar devices. So the VLSI circuits are constructed with MOS devices, especially CMOS and analyzed using different topologies. As flip-flops ar...
