中文摘要： 小波变换是20世纪80年代发展起来的应用数学分支，它具有多分辨率的特点。连续小波变换是分析非平稳信号的有力工具，在信号处理上有着广泛的应用。为了适应工程中信号处理的实时性要求，采用硬件实现连续小波变换具有重要的研究意义和应用价值。植入式系统和便携式消费类电子产品的巨大需求给集成电路的低功耗、高性能和小体积实现提出了更高要求。本项目将超低功耗模拟VLSI设计技术与小波变换理论相结合，以植入式芯片和便携式电子产品为应用背景，对连续小波变换模拟VLSI实现进行深入系统的研究。旨在用单片模拟VLSI代替数字计算，在超低功耗的条件下，实时实现信号的小波变换，促进连续小波变换在可植入式生物医学仪器、便携式电子设备等系统中的应用。

英文摘要： The Wavelet transform is a new branch of applied mathematics which has been developed since 1980s .It has characteristic of multi-resolution. The CWT(continuous wavelet transform) is a powerful tool in analyzing the unstable signals and has been wildly used in signal processing. For the real-time requirements of signal processing in engineering applications, the study of employing hardware to implement wavelet transform is of great theory significance and has value of actual using. Tremendous demands of implanted system and the portable consumer electronical products require IC to feature lower power, higher performance and smaller volume.In this project, by combining the ultra-low-power analog VLSI(Very Large Scale Integration) design technology with the CWT theory, the analog VLSI implementation of continuous wavelet transform is studied systematically, which is on the application background such as the implanted chips and the portable products. The purpose of this research is to implement the CWT using an analog chip instead of numerical computation to satisfy ultra-low-power and real-time applications such as implantable medical instruments as well as portable electric equipments, etc.
