Algorithms for Threshold Dispersion Minimization of the CHIPIX65 Asynchronous Front-End

This work discusses four different algorithms for the minimization of threshold dispersion in multichannel readout circuits for pixel detectors. These algorithms, which are based on different methods (e.g. charge scans, threshold scans, etc) and differs in terms of performance and computation time, have been tested on the asynchronous front-end integrated in the CHIPIX65_FE0, a readout ASIC prototype designed in a 65 nm CMOS technology.
