For future tracking detectors, such as LHCb Upgrade II VErtex LOcator (VELO) detector, requirements are: a <50 ps timing resolution; spatial resolution on the order of 10 um; and radiation hardness up to $6 \times 10^{16}~n_{eq}~cm^{-2}$. The TimeSPOT...

Monolithic active pixel sensors are considered for vertex or tracking detectors
of a large variety of particle physics experiments. Consequently, the design of
pixel matrices faces a wide range of specifications. That impacts in particular
the matrix read-out strategy, which is highly constrained in terms of power
