摘要
提出了一种基于电流模的开关电流技术取代基于电压模的开关电容技术实现连续小波变换的方法.采用并联式复解调方案利用开关电流技术实现连续小波变换.设计实现了开关电流振荡器和开关电流乘法器,Pspice仿真结果证实了其可行性.
This paper proposed a method for the implementation of continuous wavelet-transform （CWT） using switched-current （SI） technology, based on current mode and a substitute of switched-capacitor. The scheme of complex demodulation, using parallel architecture, was provided. The circuit design of oscillator and multiplier based on switched-current technology was presented, and its validity was proved by simulation using Pspice.
