Abstract
A domino logic technique is designed to meet the critical
concern of the VLSI era with convenience and high
microelectronic devices, power consumption of the digital
circuit. The design and circuit performance improves the
power consumption, area and delay of the circuit. If there is a
path delay in wide fan multiplexers, then path reads out
becomes more difficult and there is high power consumption
due to switching activity, also it has high noise immunity in
the dynamic gates. At a lower level, if the device operates
with better efficiency the power consumption, speed, delay
processing and power dissipation have to be sustained. To
maintain the device level proposed circuit design is
implemented, so that the voltage level is minimized. The
designed Filtered Switch Domino (FSD), Multi Dynamic
Node Domino (MDND) and measured the parameters like
power, area and delay. For further improvement both the FSD
and MDND were combined and results have been deliberate.
The experimental setup is designed by Cadence –Virtuoso
analogy tools. In domino logic circuit these techniques are
proposed to improve the performance and to provide better
results in power consumption than the existing methods.

Introduction
For high performance in integrated circuit design, we are
implementing clocked logic circuit methodology. It has been
designed to provide low-power static random access to
various applications. We perform VLSI technology with less
energy consumption, the design is implemented to reduce the
static process burden and to manage the delay of the logic
circuit. Dynamic logic of the device is exploiting from the
static logic, which deliberate the information of capacitances
in the circuit design.
Dynamic logic has been used worldwide for achieving the
high performance in VLSI devices. In an increased application
of VLSI Technology, operating the appliance with less energy
consumption as well as reduced structure is a tedious process
nowadays. Multiplexer requires a strong keeper circuits for
the compensation techniques. Charge sharing is recovered in
many of the previous work but still it creates high heat
dissipation along with increased delay in the circuit over the
devices.
Clocked Logic Circuit is rapid access than the static in
counterparts, toggle rate and power consumption. Based on
trade-offs, the consumption is defined and the toggle will be
smaller in the logic circuit. The methodology of dynamic
design is distinguished usually when it refers to logic family
like SOI design. In combinational or integrated logic circuit
the clocked logic uses the clock signal in sequential form for
synchronizing the transitions.
Wide fan-in dynamic multiplexers are used to make the
critical circuits of read-out paths in high-speed register files.
In the existing topologies new Footer Voltage Feed Forward
Domino (FVFD) and Static Switching Pulse Domino (SSPD)
designs for dynamic multiplexers are used, so that they make
the voltage swing at a high manner. Not only increasing the
keeper circuit and the Footer circuit in the read path alone can
give the solution to charge pump reduction to operate the
VLSI circuits but also alternative ways will provide different
approaches achieving this process for the charge pump. To
overcome the above stated problems, new domino logic is
designed from the existing dominos like static domino logic
which is a traditional logic system but by having more voltage
swing. In the previous topologies, dynamic multiplexers are
nearly new to make voltage swing at a high manner with new
Footer Voltage Feed Forward Domino (FVFD) and Static
Switching Pulse Domino (SSPD) designs.
In this paper, dynamic logic system FSD and MDND have
been designed to improve the performance analysis of
consumption in the VLSI device. In real time applications,
generally footer circuits are used for area selection which
consists of capacitance voltage improvement. Due to the
improvement in voltage, capacitance, area selection is
possible in footer circuits. If there are no such possibilities, an
area selection process cannot be achieved in the real time
applications.
In the traditional logic system a new logic circuit is designed
from existing dominos which have more voltage swing. New
domino logics called Filtered Switch Domino Logic (FSD)
and Multi Dynamic Node Domino (MDND) are designed
through a transistor level for the correct operations, which
provides high speed, dependable operation, which has a
smaller area than the static gates and lesser parasitic
capacitances, compared to the traditional method, which is in
practice. Also low power domino logic circuit techniques
were also designed, which can able to control and minimize
the leakage current and power delay. The proposed work is
