چکیده

In this paper, an analog implementation of the Wavelet Transform is presented. The circuit is based on the Dynamic Translinear circuit technique. From simulations, it is demonstrated that we can scale and shift in time by simply controlling the capacitance or the control current values. The advantage of this topology is the lowpower consumption. The circuit operates from 1-V supply voltage and a bias current of 1μA.
