Abstract
A readout integrated circuit (IC) architecture for a tunnelling magnetoresistive (TMR) sensor which uses common mode feedback to achieve a performance level suitable for accurate detection of biomagnetic signals. The architecture uses a three-operational amplifier configuration with chopper stabilization. The architecture may form part of a fully integrated biomagnetic sensor electronics package that includes an array of TMR sensors together with modules for signal amplification and conditioning, data conversion and communication.
