Abstract :

The Aim Of This Research Proposal Is To Design And Build Dynamic Comparator That Outperforms The Conventional Strong-Arm Latch (single Tail Comparator And Double-tail Latched Comparator) In Terms Of Delay And Power Efficiency. A Comparator Plays An Important Role In Designing The Desired High-resolution, High-speed And Low Power Analog-to-digital Data Converter. Among Different Architectures, CMOS Dynamic Latched Comparators Find Wide Usage In Analog-toDigital Converters (ADCs) Thanks To Their High-speed, Low Power Consumption And Ability To Produce Rail-to-rail Outputs. The Strong-Arm Latch Is One Of The Most Common Dynamic Comparators Used In ADC Designs. In This Research Proposal, An EI-zakker Comparator For High Speed And Low-power Dynamic Comparator Topology Is Proposed And Compared To The Conventional Strong ARM Latch Type Of Single Tail And Double Tail Latch In Terms Of Delay, Power Consumption And Speed. Simulation Results Show That The Proposed Architectures Consume 40% To 50% Less Power Than The Strong-Arm Latch For The Same Input Referred Voltage Of 1.8v. Additionally, The Speed Of Proposed EI-Zakker Comparator Design Is Insensitive To Input Common-mode Variation And Outperforms The StrongArm Latch Type For Low Vcm (common Mode Voltage) Values. The Strong-Arm Latch Types And Proposed EI-Zakker Comparator Architecture Are Simulated On The Same Technology Using 180nm TSMC CMOS Technology. The Measurement Results Confirmed The Better Performance Of The Proposed Designs By Showing 46% Less Power Consumption Than The Strong-Arm Latch Type Of Single Tail And Double Tail Comparators With Similar Input-referred Voltage. The Proposed EI-Zakker Topology Offers A Low-power, Wide Common-mode Input Range Solution For High-precision Comparator Design. Keywords— Comparator, Strong ARM Comparator, CMOS, EIZakker Comparator, Double Tail Latch Type Comparator, Low Power.
