Sensor readout circuit for a biomagnetism measurement system

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 stabiliz...
