Apstrakt:
In this paper, a low voltage system for magnetic field sensor is being proposed. The complete system is working with 1.5 Volt single power supply. The system is composed of two main components. The first component is the magnet field sensor using AMR technology with an integrated compensation coil. The second part is an operational amplifier which needed to amplify the output signal from the sensor. The amplified signal then is being sent back to the integrated compensation coil inside the sensor to generate a new magnetic field cfor compensating the magnetic field ) sensed by the sensor. This Hc introduces a negative feedback to the system. With this technique we can have a sensor system with a high accuracy. The system performances are evaluated by simulation.
