Ultra Low-Voltage Ultra Low-Power Sinh-Domain Wavelet Filer for Electrocardiogram Signal Analysis

摘要

An ultra low-voltage and low-power Sinh-Domain Wavelet filter, for ECG signal analysis, is introduced in this paper. Attractive offered benefits are the capabilities for achieving resistorless realizations with electronic adjustment of frequency characteristics, and operating in a low-voltage and low-power environment essential for biomedical signal analysis. In addition, the inherent class-AB operation of Sinh-Domain filters offers the capability for handling signals greater than the bias current, leading to a power saving. The aforementioned benefits have been evaluated through simulation results, using the Analog Design Environment of the Cadence software.
