Active RC Electronic Biquad/Universal Self Compensated Filters
2° order, 3 base-stages biquad/universal continuous time analog active filters type resonant and, more particulary, active full self-compensation techniques to improve the frequency range, the stability and/or the selectivity of the filters themselves with a very low, or as if zero, cost. These active filters techniques are the only ones that can (fully) erase the parasitic poles using a single resistor or an additional operational amplifier which has a functionally filtering output. This patent extends to Italy(priority ITMI20031566 A1).
