Abstract

Gaussian functions are extensively used in the field of wavelet transform and pattern recognition. In this paper, a fully-programmable analog circuit for Gaussian function generator using switched-current (SI) technology is proposed. SI circuits are well suited for this application since the programmability can be implemented and controlled by the clock frequency and the transconductance ratios of SI filters precisely and easily. On the basis of central limit theorem, we synthesize the Gaussian function with the cascade of several low-pass filters, implemented by SI circuits. Theoretical analysis and simulation results show that the proposed method is feasible.
