A set of innovative active pixel architectures has been conceived and implemented in standard CMOS technology. Active circuits are introduced into the pixel, to increase S/N ratio and to perform basic signal processing. Testing of such devices, however, becomes critical, due to the circuit relative complexity and to the need of accurately evaluating timing and position of the impinging radiation. A test strategy has thus been devised, exploiting a NIR laser source, which has been carefully characterized and tuned. The NIR laser allows for emulating, in a much more controllable fashion, a MIP event. This allow for validation of novel …

This paper aims at exploring and validating the adoption of standard fabrication processes for the realization of CMOS active pixel sensors, for particle detection purposes. The goal is to implement a single-chip, complete radiation sensor system, including on a CMOS integrated circuit the sensitive devices, read-out and signal processing circuits. A prototype chip (RAPS01) based on these principles has been already fabricated, and a chip characterization has been carried out; in particular, the evaluation of the sensitivity of the sensor response on the actual operating conditions was estimated, as well as the response uniformity. Optimization and tailoring of the sensor …
