An electronic gyrator

After a brief introduction to the gyrator concept, its realization as an accurate monolithic integrated circuit is described. The inherent electronic problems are considered and performance criteria are defined. Data are given. Applications, particularly in electric filters, are discussed and it is shown that in the lower frequency range the use of these `semifloating´ gyrators can be very advantageous. The monolithic integration of the gyrator can be seen as a major step toward integrated selectivity.
