Abstract Low-Gain Avalanche Diodes (LGAD) are silicon detectors with output signals that
are about a factor of 10 larger than those of traditional sensors. In this paper we analyze how
the design of LGAD can be optimized to exploit their increased output signal to reach
optimum timing performances. Our simulations show that these sensors, the so-called Ultra-
Fast Silicon Detectors (UFSD), will be able to reach a time resolution factor of 10 better than
that of traditional silicon sensors.
