Abstract :
A new general structure for continuous-time deconvolution filters is presented. It is based on the approximation of the impulse response by a sum of weighted exponential functions. The circuit uses multiple-loop feedback without introducing any stability problems. It offers unity DC gain and tunability of all the fitting coefficients, while keeping simplicity, flexibility and robustness.
