Abstract :
Doubly terminatéd LC filters realised with simulated inductances are considered by some authors to have particularly satisfactory sensitivity characteristics. The paper provides an analytical comparison of the sensitivity characteristics obtainable with such filters and with a cascade of 2nd-order active sections. The results confirm that the simulated-inductance filter can be realised with a limited improvement in sensitivity. It is hoped that this quantitative treatment will allow the designer to decide whether or not the improvements in sensitivity offered by inductance-simulation techniques outweigh other disadvantages inherent in their realisation.
