VLSI Implementation of Power Efficient 4-bit Flash ADC

Abstract

The project aims to design and implement a 4-bit Thermometer-coded Flash Analog-to-Digital Converter (ADC) using Very Large-Scale Integration (VLSI) technology. The proposed design employs a high-speed, fully parallel architecture that uses a resistor ladder network to generate the reference voltages for flash comparison. The ADC will be implemented using the 180 nm CMOS technology node, and simulation results will be obtained using Cadence Virtuoso tools. The performance of the design will be evaluated based on several metrics, including resolution, speed, power consumption, and accuracy. The project aims to achieve a high-resolution, high=speed ADC with low power consumption that is suitable for use in various applications, such as digital signal processing, data acquisition, and instrumentation. The results of this project can contribute to the development of advanced ADC designs and enhance the performance of various electronic systems.
