Simulation results show that the proposed pass transistor based D flip-flop circuit has the least leakage power dissipation. In the case of shift registers the combined stack and reverse body bias method gives
CMOS SR Latch based on NAND Gate is shown in figure.Depletion-load nMOS SR Latch based on NAND Gate is shown in figure. The operation is similar to that of CMOS NAND SR latch. The CMOS circuit implementation has low static power dissipation and high noise margin....
In this paper, we present a multi-level graph partitioning algorithm for circuit partitioning, which will minimize the number of test vectors during a low power test in VLSI circuits. By reducing the number of test vectors, we can reduce the energy consumption during the test. Our experimental...
Latch Design Jamb latch: uses a weak feedback inverter in place of the tristate. + reduces the clock load + saves two transistors requires careful circuit design 11: Sequential Circuits Jamb latch used in register files and Field Programmable Gate Array (FPGA) cells 11: Sequential Circuits ...
The practicalities of vlsi design make regularity attractive, and we describe the use of familiar higher order functions to capture spatial iteration.By reasoning about circuits rather than signals (programs rather than data) one abstracts from the sequential nature of a circuit. By reasoning about ...
A static latch circuit. Dynamic registers are small and consume little power. However, the value can be corrupted by leakage of charge from the gate capacitance. Charge in capacitors is subject to leakage over time. When enough charge leaks away, a 1 degrades to an X or 0. The charge ...
A serial multiplier suitable for VLSI implementation is discussed. The multiplier accepts binary operands supplied in a serial fashion, least significant bits first. The multiplier uses a canonical cell which allows calculation of a 2k length product with only k identical cells. These cells utilize ...

Research and development in the area of path-delay faults is gaining importance as the speed of VLSI circuits continues to increase. Path-delay faults can arise from both manufacturing process parameter variations as well as spot defects in a circuit. Unlike stuck-at faults which require only a...
