Using a Second Order Sigma-Delta Control to Improve the Performance of Metal-Oxide Gas Sensors
Controls of surface potential have been proposed to accelerate the time response of MOX gas sensors. These controls use temperature modulations and a feedback loop based on first-order sigma-delta modulators to keep constant the surface potential. Changes in the surrounding gases, therefore, must be...
