High speed and low power double tail comparator for ADC application using 0.13um technology / Nur Fauzana Taib

Analog to digital converters (ADCs) is an electronic integrated circuit for converting a signal from analog to digital form. ADCs converts analog signal into digital data that can be processed by computers for various purposes. The main purpose of the ADCs is that to digitize the analog signals, which means to record and store the analog signals in numbers. Comparator is electronic devices which are mainly as a part of analog to digital converter. This project proposes design Double – Tail Comparator for analog to digital converters (ADCs) application. This design gives better performance of the comparator by minimizing the propagation delay and the power consumption. The schematic design for this proposed design is obtained using 0.13 µm technology with supply voltage of 1.8 V and the operating frequency of 800 MHz. The design is carried out using Mentor Graphics tools with Silterra 0.13 µm technology files. The schematic design and simulations is performed using Mentor Graphics Design Architect tool. At the end of this project, the proposed design results to reduce the propagation delay and the power consume for the comparator circuit which is very important issues for various applications in electronics design.
