signal specific successive approximation analog to digital converter
چکیده: در میان انواع متفاوتی از مبدل های آنالوگ به دیجیتال که تا کنون معرفی شده اند، مبدل های آنالوگ به دیجیتال تقاریب متوالی(sar ) به علت سادگی ساختار و همچنین توان مصرفی کم، همواره یکی از پرکاربرد ترین مبدل های آنالوگ به دیحیتال در کاربرد های بایومدیکال بوده اند. به همین دلیل تاکنون روش های متعددی برای کاهش هرچه بیشتر توان مصرفی در این مبدل ها ارائه شده است که در اکثر آنها توجهی به مشخصات سی...
15 صفحه اولCapacitor mismatch error cancellation technique for a successive approximation A/D converter
An error cancellation technique is described for suppressing capacitor mismatch in a successive approximation A/D converter. At the cost of a 50% increase in the conversion time, the first-order capacitor mismatch error is cancelled. Methods for achieving top-plate parasitic insensitive operation are described, and the use of a gain-and offset-compensated opamp is explained. SWIT-CAP simulation...
متن کاملSelf-Oscillating Switched-Capacitor DC-DC Converter
Recent advances in low-power circuits have enabled mm-scale wireless systems [1] for wireless sensor networks and implantable devices, among other applications. Energy harvesting is an attractive way to power such systems due to limited energy capacity of batteries at these form factors. However, the same size limitation restricts the amount of harvested power, which can be as low as 10s of nW ...
متن کاملA Switched-Capacitor Three-Phase AC-AC Converter
The main objective of this paper is to replace autotransformers and transformers in industrial applications by switched capacitor three phase AC-AC converters. The control system is not required in case of open loop operation of AC-AC converters. In this paper, by employing closed loop system, the advantages such as accuracy, reduced error, reliability, fast response and less noise can be ensur...
متن کاملAn ultra low-power low-voltage switched-comparator successive approximation analog to digital converter
A 9-bit ultra low-power successive approximation analogto-digital converter (SA-ADC), which is able to operate at very low supply voltage, is presented. The low power consumption is achieved by using new switched-comparator architecture. In the proposed architecture the comparator, which is one of the most power hungry blocks of the SA-ADC, is switched off after the decision-making interval as ...
