Abstract
This paper presents experimental results and analyses of a resistive transducer, a photoresistor, with an Active-Pixel Sensor (APS) circuit, widely used in image sensors. The pixel circuit is equipped with a transfer-gate switch to keep the signal constant in the read node. This particular circuit-sensor configuration has not been found in the literature, and can be designed for applications with a variety of detectors with variable resistives characteristics, beyond the scope of photosensitivity.
