ACTIVE FILTERS USING SIMULATED INDUCTANCE.

Abstract

Active circuits for simulating inductance are described which can be used as direct replacements for the inductors in passive LCR filters. The method of realisation is based on the analogy between the relationship i = 1/L integral Vdt for an inductor and the transfer function V sub o/V sub i = -1/pT for an electronic feedback integrator. The use of a constant current source is avoided and the three variations given may be built up from active circuits having many other applications. (Author)
