Active RC Electronic Biquad/Universal Self-Compensated Filter(s)

2° order biquad/universal continuous time IF (Intermediate Frequency) 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 cost.
These active filters techniques are the only ones that can totally erase the effects of the parasitic poles, using a single resistor or an additional operational amplifier that has a functionally filtering output.

APPLICATIONS: IF Radio Receivers, Electronic Measurement Instruments, Telecommunications and all the cases wherein a High Precision Signal Filtering Process is needed to Transmit Data.

This Technology is fully Patented, the Best and the only one of his kind in the World.
