This paper presents an analog-to-digital converter with a novel adaptive wavelet-based sampling scheme. The proposed algorithm uses the wavelet transform to localize critical points in the signal, while the estimated Lipschitz exponent describes the signal's shape. Also, a polynomial reconstruction method is proposed and applied to the converter's outputs for a test signal. Results show that it is...
Signal processing by means of analog circuits offers advantages from a power consumption viewpoint. A method is described to implement wavelets in analog circuits by fitting the impulse response of a linear system to the time-reversed wavelet function. The fitting is performed using local search involving an criterion, starting from a deterministic starting point. This approach offers a large...
