Evaluating the Frequency Limitations of Operational Amplifier RC Networks by the Dominant-Pole Technique

  • Suhash Chandra Dutta RoyEmail author


A general computer-based technique is given for investigating the high-frequency performance of second-order active RC networks employing an arbitrary number of operational amplifiers. It uses the dominant-pole technique for finding deviations in Q and ω0 from their nominal values as a function of the gain bandwidth product of the operational amplifiers. The technique is applied to active RC circuits simulating a nonideal grounded inductance and curves are given for the highest usable frequency for permissible deviation in Q and ω0 for some typical circuits.
