Abstract :
The parasitic effects and tuning limitations that nonideal integrators have on continuous-time filters are discussed. The nonideal integrator is modeled to have finite DC gain and a single nondominant pole. The performance of an adaptive tuning system on tuning a continuous-time filter with nonideal integrators is compared to that of the popular approach of tuning only the poles of a transfer function. Simulation results are presented showing that the adaptive tuning system significantly reduces parasitic effects
