Design Of Sar-Adc Based Mixed Signal Architecture For Low Power Application

Abstract

The wearable devices became wide wont to monitor body signals for long health care and residential care applications because of the speedy development of moveable natural philosophy. They sight very important signals through physiological sensors and so transmit them to a cloud info for analysis and watching functions through wireless communication systems. A sensible digitizer (ADC) was accomplished by a mixed-signal application-specific integrated circuit (ASIC) that is intended supported adaptive resolution and lossless compression techniques for graph (ECG) signal watching. The adaptive resolution technique is employed to pick out totally different sampling frequencies of the ADC consistent with amplitude changes within the input signals. Consistent with the characteristic of the signals the sampling clock for the ADC are often adaptively elect. Data compression techniques used are economical methodology to avoid wasting transmission power by reducing the number of knowledge being transmitted over the network. The signal transmission rate has been reduced and maintained high-quality detection and meets the low power consumption of the planning. The ADC application of mixed signal design is implemented using VHDL coding.
