Voltage Measurements in Biomedical Research

How FET-Input IC Op Amps Can Help—A Brief Summary

The problem is easily stated but wicked to solve: One must measure a (small) voltage occuring between two points in an entity under test safely and with reasonable accuracy and fidelity. The sources of trouble are three-fold: the entity itself (including the measurement electrodes), the amplifier that acquires and processes the measurment, and the interconnection (and interacton). Read full article
