This paper will present experimental results of a slightly modified Active-Pixel Sensor (APS) circuit operating in cryogenic temperatures such as 77K, 40K, 20K and 8.8K. The optical sensor used was a silicon photodiode with its integrated electronics in a CMOS 0.35µm technology. Active pixel circuitry with a small number of transistors is important and widely used in image sensors. A modified APS...
This paper presents experimental and simulated results of an Active-Pixel Sensor (APS) circuit operating at different temperatures (300K, 77K, 60K and 40K). The optical sensor used was a silicon photodiode integrated with its electronics in a standard CMOS 0.35µm technology. Interestingly, the pixel worked well at all temperatures tested. These first experimental results are very promising for future...
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...
