摘要：

Implementation of Morlet wavelet using current mode circuits is presented in CMOS technology. The circuit consists of four main building blocks: squaring circuit, exponential function generator circuit, Gaussian function generator circuit and analog multiplier circuit. The proposed structure is fully programmable in terms of standard deviation and peak gain of the Gaussian function. Therefore Morlet wavelet can be programmed to define different scaling kind shifting parameters. Simulation results of the circuits are obtained by HSPICE in 0.35 mu m standard CMOS process. Simulated results verify the feasibility of both the wavelet realization and proposed circuits.
