Abstract :
This paper will present experimental results of a slightly modified Active-Pixel Sensor (APS) circuit operating in cryogenic temperatures such as 77 K, 40 K, 20 K and 8.8 K. The optical sensor used was a silicon photodiode with its integrated electronics in a CMOS 0.35 μm technology. Active pixel circuitry with a small number of transistors is important and widely used in image sensors. A modified APS with five transistors was designed and tested under visible light at low temperatures in order to assess its hybrid further use with III-V infrared quantum detectors, which operate at these temperatures.
