A Low Power Comparator Design for 6-Bit Flash ADC in 90-Nm CMOS
The main focus of this paper is to design a “Low power Flash ADC” for ultra-wide band applications using CMOS 90nm technology. Flash ADC consists of a reference generator, array of comparators, 1-out-of N code generator, Fat tree encoder and output D latches. The demanding issues in the design of a low power flash ADC is the design of low power latched comparator. The proposed comparator in thi...
متن کاملLinköping University Post Print A 6‐bit 2.5‐GS/s Flash ADC using Comparator Redundancy for Low Power in 90nm CMOS
A 2.5 GS/s flash ADC, fabricated in 90nm CMOS utilizes comparator redundancy to avoid traditional power, speed and accuracy trade-offs. The redundancy removes the need to control comparator offsets, allowing the large process-variation induced mismatch of small devices in nanometer technologies. This enables the use of small-sized, ultra-low-power comparators with clock-gating capabilities in o...
متن کاملA SoC based low power 8-bit flash ADC in 45 nm CMOS technology
In modern VLSI design the transistor sizing and scaling has an considerable impact. There are very essential two constrains, which needs serious attention to the VLSI chip designer are high speed and low power consumption. Therefore in this paper an 8-bit 3 Gs/sec flash analog-to-digital converter (ADC) in 45nm CMOS technology is presented for low power and high speed system-on-chip (SoC) appli...

+ Katholieke Universiteit Leuven, Kasteelpark Arenberg 10, B-3001 Heverlee, [email protected] . Abstract The design plan and measurement results of a very high-speed 6 bit CMOS Flash ADC converter are presented. The very high acquisition speed is obtained by improved comparator design. At these high frequencies power-efficient error correction logic is necessary. Measurements show th...
متن کاملDesign 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...
