Abstract

A low noise integrated circuit with powerline noise reduction technique for current drive magnetic permeability interference (CDMPI) sensor was designed, which integrated the required driving and readout circuits. The sensitivity of the sensing system reached 10^-9-10^-10 T without averaging. The result showed the potential use of the sensor for the weak field measurements, such as magnetocardiography.
