A Survey Analysis on CMOS Integrated Circuits with Clock-Gated Logic StructureIJERA Editor
Various circuit design techniques has been presented to improve noise tolerance of the proposed CGS logic families. Noise in deep submicron technology limits the reliability and performance of ICs. The ANTE (Average Noise Threshold Energy) metric is used for the analysis of noise tolerance of proposed CGS. A 2-input NAND and NOR gate is designed by the proposed technique. Simulation results for a 2-input NAND gate at clock gated logic show that the proposed noise tolerant circuit achieves 1.79X ANTE improvement along with the reduction in leakage power. Continuous scaling of technology towards the manometer range significantly increases leakage current level and the effect of noise. This research can be further extended for performance optimization in terms of power, speed, area and noise immunity.

24. Pass Transistor Logic(PTL)
• Only N_MOS Transistors are Used to design the logic.
• Input Signals are Applied to both Gate and
Drain/Source.
When A=1 Upper NMOS is ON, So
o/p is F=B
When A=0 Upper
NMOS is ON, So o/p is F=B
25. CMOS Transmission Gate
Actually, It is a Parallel Connection of
N_MOSFET and P-MOSFET that realizes a
simple switch.
Inputs to the gates of N-MOSFET and P-
MOSFET are Complementary to each other.
26. Working of CMOS Transmission Gate
Case-1
When C=1 and C^=0
Both NMOS&PMOS--------ON
Nodes A&B-----------Short Circuited
Input Logic is Transferred to Output
Case-2
When C=10and C^=1
Both NMOS&PMOS--------OFF
Nodes A&B-----------Open Circuited
Actually ,this is Called High-Impedance State.
34. Description
It is used as a supplement for the CMOS logic circuits.
In the pseudo-NMOS logic, the PUN is realized by a
single PMOS transistor.
The gate terminal of the PMOS transistor is connected
to the ground.
P-MOS Transistor remains permanently in the ON state
Depending on the input combinations, output goes low
through the PDN.
Only the NMOS logic (Qn) is driven by the input
Voltage
Qp acts as an active load for Qn.
Except for the load device(P-MOS), the Pseudo-NMOS
gate circuit is identical to the pull-down
network(PDN) of the CMOS gate.
36. Advantages & Disadvantages of Pseudo N-MOS Logic
Advantages:
1) Uses less number of transistors as compared to
CMOS logic.
2) Geometrical area and delay gets reduced as it
requires less transistors.
3) Low power dissipation.
Disadvantages
1.The main drawback of using a Pseudo NMOS gate
instead of a CMOS gate is that the always on PMOS
load conducts a steady current when the output
voltage is lower than VDD.
2.Layout problems are critical.
38. Description
It is one of the alternate method of reducing
Transistor Count.
It is similar to Pseudo –NMOS Logic except one
additional NMOS Transistor(MN) Connected between
PDN and Ground.
PMOS Transistor in PUN and additional NMOS
Transistor(MN) in PDN are Operated by a Clock Signal
ϕ.
Dynamic Logic Circuit Operates in 2 Phases of Single
Clock Pulse ϕ
Phase-1 (Pre-Charge Phase ϕ =0)
Here, Output is Pre Charged to Logic High Level.
Phase-2 (Evaluation Phase ϕ=1)
Here, Output is evaluated based on applied Input Logic.
42. General form of CMOS Domino Logic
(Dynamic Logic + Inverter)
ϕ
43. Description
It is a Slightly modified Version of Dynamic CMOS
Logic Circuit.
A Static Inverter is Connected at the Output of
each dynamic CMOS logic blocks.
Addition of Inverter Solves the Problem of
Cascading of dynamic CMOS logic Circuits.
It is Suitable for only Non-Inverting Logic(the
expression having no complement over whole
expression)
For Inverting the logic the expression must be
reorganized before it can be realized using
Domino CMOS Logic.
44. Working
Case -1 when ϕ = 0
Output is Pre charged to logic high and O/P of static
Inverter is Low.
Case -2 When ϕ =1
O/P is either 0 (or) 1 Output of static Inverter
can make 0 1 in Evaluation. So, Irrespective of I/P
and O/p of Static Inverter can’t make 1 0 in
Evaluation Phase.
Note:
For, N- Input Logic function we require,
2N Transistors-- Static CMOS
N+2 Transistors- Dynamic CMOS
N+2+2 Transistors Domino CMOS
47. Description
A pull-up p-block and a complementary n-block pull-
down structure represent p and n-transistors
However, the logic in this case is connected to the
output only during the ON period of the clock.
Working
When ø = 1 the circuit acts an inverter , because
transistors Q3 and Q4 are ‘ON’ .
It is said to be in the “Evaluation mode”. Therefore
the output Z changes its Previous value.
When ø = 0 the circuit is in hold mode, because
transistors Q3 and Q4 ‘OFF’ .
It is said to be in the “Pre Charge mode”. Therefore
the output Z remains its previous value.
49. Description
In this, logic the actual logic blocks are
alternatively ‘n’ and ‘p’ in a cascaded structure.
The clock ø and ø^ are used alternatively to fed
the Pre Charge and Evaluate transistors.
50. Disadvantages of N-P CMOS Logic
Here, the P-tree blocks are slower than the
N-tree modules, due to the lower current drive
of the PMOS transistors in the logic network.
