The Active Inductor [A Circuit for All Seasons]
Behzad Razavi
Abstract
Reports on the technology of active inductors, inductorless circuits whose impedance rises with frequency across some frequency range. Occupying much less area than a passive inductor and offering tunability, such a circuit proves useful in broadening the bandwidth or realizing other functions that require an inductive element.
