Abstract

The following paper presents the idea of the active integrator circuit based on inductive and resistance components. Such design allows to eliminate the time drift of the circuit, which is undesired phenomenon resulting from capacitive components utilized in classic constructions. This type of integrator circuit can be used to develop the drift-free fluxmeter for investigation of ferromagnetic hysteresis phenomenon in soft magnetic materials. The paper presents concept of the integrator circuit. The SPICE simulations was performed to validate the presented idea. Finally the developed solution was tested and obtained results confirm the correctness of the integrator circuits operation.
