TIQ flash ADC with threshold compensation

Also Available Domains Transistor Logic|Cadence EDA

Project Code :TVPGTO586

Objective

The main aim of this project is to analyze the performance of flash ADC using Threshed hold inverter quantizer based comparator.

Abstract

Threshold Inverter Quantizer (TIQ) is a novel idea which can effectively replace the reference voltage generator, resistive/capacitive voltage divider network and array of differential comparators in a conventional flash Analog to Digital Converter (ADC) by an internal reference comparator array constructed of Complementary Metal Oxide Semiconductor (CMOS) inverters. The inverter threshold voltage serving as the reference voltage, this architecture claims large improvements in terms of silicon area, power consumption and operating speed. Perturbations due to sensitivity of the inverter threshold voltage to operating temperature/process variations pose impediments in such ADC designs and strongly demand a compensation scheme to such variations.
