A NOVEL LOW-POWER HIGH-SPEED CMOS COMPARATOR FOR PRECISE APPLICATIONS
M. MOUNIKA, M. APPARAO
Abstract
The process of converting
analogue signals to digital signals widely uses
comparators. Comparators are the fundamental
components of many types of ADC (Analog to
Digital Converters). In order to improve their
performance, many structures have been
presented. Performance of a comparator is
strongly affected by powers, delayed, offsets,
and noises. A novel Low-Power High-Speed
CMOS (Complementary Metal Oxide
Semiconductor) Comparator for Precise
Applications is presented in this analysis. The
decision stage and hold stage are the two stages
that make up this dynamic comparator for
Complementary Metal Oxide Semiconductors
(CMOS). Three different phases are used to
operate the comparator. Which maintains the
results of an evaluation for a defined time
interval, reset is the initial phase, decision or
evaluation is the second phase and hold is the
third. Energy efficiency can be increased while
overall power usage is decreased. The length of
time that the presented comparator is in a low
state is important. The 16.1 version of 18nm
technology will be used to build this
comparator’s design, which will result in a
significant improvement in power and delay.
According to the results, the provided
comparator performs better than the NMOS (Nchannel Metal Oxide Semiconductor) and
PMOS (P-channel Metal Oxide Semiconductor)
comparators in terms of power dissipation and
time delay
