Abstract
The four Multiple-Input Operational Transconductance Amplifier (MI-OTA) used in this paper's electronically tunable three-input, single-output fully differential universal filter is built using two commercially available integrated circuits (ICs) (LM13700), two capacitors, and two resistors. The proposed circuit provides all five standard filter functions; it is possible to select one without modifying the circuit topology by adjusting the input signal condition. The features of the circuit are the ability of the natural frequency and quality factor, which can be tuned via the capacitor. Included are the simulation results, which validate the suggested circuit's operation. The data presented closely aligns with the theoretical prediction.
