Title
Cmos Microsystem Front-End For Microtesla Resolution Magnetic Field Measurement
Abstract
In this paper we discuss the conception and performances of a monolithic microsystem for magnetic field measurement built in standard 0.6 mum CMOS technology. It is shown that 5.2 microTesla resolution over 1 kHz bandwidth (5 to 1 kHz) can be achieved by combining a smart Hall effect based sensing device and appropriate analog conditioning electronics. The study focuses on the methods used to drive up the sensor's sensitivity and to drive down the system's noise level in order to achieve the above-mentioned resolution. A new circuitry is proposed for biasing the sensor.
