Brief report introduces 14 new circuit configurations using two CFOAs and three passive elements, indicating practical applications.
The main object of this brief report is to introduce 14 new floating immittance (FI) configurations each employing only two current feedback op‐amps (CFOA) and canonical number of only three passive elements, as an addition to the seven such circuits known earlier. The results of some SPICE simulations and hardware experimental results, based on the commercially available AD844‐type integrated circuit CFOAs, have been given to demonstrate the workability of the presented new FI circuits.
