DESIGN, IMPLEMENTATION AND ANALYSIS OF FLASH ADC ARCHITECTURE WITH DIFFERENTIAL AMPLIFIER AS COMPARATOR USING CUSTOM DESIGN APPROACH

Design of Flash ADC using Improved Comparator Scheme

This Paper introduced a 4 bit Flash Analog to Digital converter. The propose ADC consist of the comparators and the MUX based decoder. Propose Comparator eliminate the use of resistor ladder in the circuit. All the input of comparators are connected to the common input node. Depending upon the internal voltage of comparator and the input voltage output may be “0” or “1” known as thermometer cod...

Design of a 45nm TIQ Comparator for High Speed and Low Power 4-Bit Flash ADC

The continued speed improvement of serial links and appearance of new communication technologies, such as ultra-wideband (UWB), have introduced increasing demands on the speed and power specifications of high-speed low-tomedium resolution analog-to-digital converters (ADCs).This paper presents the design of high speed and ultra low power comparator of a 4-bit ADC. The comparator used is Thresho...

Low Power Encoder and Comparator Design of 5-bit Flash Adc

Design of 32nm CMOS EIS Comparator for N-Bit Flash ADC

The design methods and optimization of the 32nm CMOS EIS (Efficient Inverter scheme) comparator circuit for an N bit flash A/D converter are presented in this paper. Flash A/D converter requires 2 n -1 comparators. Each one different from all others depends on the particular design. The used analog power supply in this comparator is only 1V. Low voltage analog design is necessary to compile so ...
