Active LR Integrator Circuit with Ferrite Core

Piotr Gazda , Michał Nowicki , Maciej Kachniarz


The paper presents the idea of active LR integrator circuit based on ferrite core. The LR topology, in contrast to contemporary RC, allow for drift-free operation of the integrator. Presented circuit is intended as main component of continuous operation fluxmeters and magnetoelastic transducers, especially working with low frequency signals. Critical component for proper frequency range and low signal distortion is the core material, which should allow for close-to-ideal inductance in the circuit. Presented simulation, measurement results, and total harmonic distortion analysis show that the proposed circuit works correctly.
