Paper Abstract

To meet the ultra low-power and low-voltage applications,this paper presents a analog VLSI implementation of DOG wavelet transform using a balanced log-domain integrator with class AB. The circuits of implementing wavelet transform are composed of analog filter ,whose impulse response is the required wavelet . Levenbery-Marquardt nonlinear least square method is employed to obtain the transfer function of the filter.The filter design is based on IFLF structure with balanced log-domain integrators as the main building blocks.By changing the values of the log-domain integrators bias currents, this circuit can realize various scales wavelet transform. And the validity of the proposed method is confirmed by Pspice simulation results.
