Abstract

A general method for analogue implementation of high-frequency wavelet transform is proposed in which the wavelet transform is synthesized by a bank of Gm-C bandpass filters whose impulse responses are the mother wavelet and its dilations. The proposed approach employs the inverse follow-the-leader-feedback multiple loop feedback structure for filter design to lower the magnitude sensitivity and facilitate the arbitrary rational function realization. The Marr wavelet is used as an example in this paper to illustrate design details. The wavelet filter is simulated using TSMC 1.8V 0.18μm CMOS technology. Simulation results show performance values obtained.
