Opis

Filters of some sort are essential for extracting proper signals for most the electronic circuits. It is, therefore, in the interest of anyone involved in electronic circuit design to have the ability to develop filter circuits capable of meeting a given set of specifications. A novel approach has been made to realize floating inductor. The circuit implementation is based on the use of operational transconductance amplifier (OTAs) as an active element along with a grounded capacitor. The floating inductor requires 3-OTAs. The resulting inductance can be electronically adjusted precisely by varying external bias current accordingly. Different topologies of the filters are designed as per their need and the applications. Filters can be classified on the basis of response characteristics, components used, signals used, or mathematical approximations. The network of the 3rd and 5th order Chebyshev filter has been chosen and all the passive components, like resistors and inductors are implemented using the active device (OTA).
