Research paper thumbnail of Novel voltage-controlled conditioning circuit applied to the ISFETs temporary drift and thermal dependency

Sensors and Actuators B-chemical, 2003

The novel conditioning circuit allows the sensor polarization with the needed either voltage or current required in each application, thanks to two completely independent voltage-controlled blocks (current and voltage blocks). The control of the voltage block is the most critical point in our design because the voltage block maintains the sensor feedback stable, avoiding the thermal and temporary drifts of the sensor feedback. #
