Abstract

Generalized impedance converters (GIC) are electronic circuits which have been widely used as controllable impedance in AC regime, especially in active filter synthesis. In the work presented, the GIC is used as a biasing circuit of a magnetoresistive current sensor (Wheatstone bridge) which is located inside the GIC itself. In this case, the GIC works under DC bias unlike its usual AC bias use
