Some Recent Contributions to Inductor Simulation and Applications to Low-Sensitivity Biquad Design

  • Suhash Chandra Dutta RoyEmail author


Following a brief discussion on the advantages of inductor simulation approach to active filter design, some recent circuits for grounded as well as floating inductors are discussed. The application of simulated inductors to insensitive biquadratic design is illustrated by reference to two recently published techniques.
