The Apsel65 front-end chip for the readout of pixel sensors in the 65 nm CMOS node

This work is concerned with the design criteria and the experimental characterization of front-end electronics in a 65 nm CMOS technology for the readout of hybrid pixels and of monolithic active pixel sensors using a deep N-well as their collecting electrode. The work will present a summary of the experimental results relevant to a prototype chip, named Apsel65, focusing particularly on the front-end processor features and performance.
