Inverse filters are widely used in various control, instrumentation and communication systems to correct the distortions of signals caused by signal processing or transmission systems. In this paper present a novel approach multi-function inverse biquad configuration based on current feedback operational amplifiers (CFOAs) and grounded passive elements. The proposed configuration is used to realize inverse lowpass, inverse bandpass and inverse highpass filter functions. The relevant coefficients of the inverse filters are orthogonal adjustable by independent passive elements. All the passive elements in the proposed configuration are grounded to benefit easier electronic tunability.
