Active RC Filters Using a Single Differential Input Operational Amplifier
Spandan Roy · IETE Journal of Research · 1972
A procedure, alternative to that proposed by Mitra, is given for realizing any real rational transfer function by using RC one ports and a single differential input operational amplifier. It is shown, with the help of examples, that the new procedure admits of much more flexibility in the choice of element values than Mitra's method.
