ABSTRACT

This paper presents theoretical and computer simulation results which show the pole position of the integrator circuits in one of the most important distortion sources in gradient-search-based analog adaptive systems. A new integrator structure, suitable for adaptive filtering applications is also proposed, whose performance is compared with other previously proposed integrator circuits operating in an adaptive filtering framework.
