Abstract :
In this article, a parameter-varying lowpass filter whose transient response has a reduced duration is presented. The compensation of its transient behaviour is done by means of a temporary increase of the filter parameters. The proposed filter is implemented by means of OTAs and capacitors. The resulting circuit is used in the implementation of a fourth-order Chebyshev filter with appreciable ringing. Simulation results are used to verify the performance of the filter.
