  A pico-second timing (PIST) front-end electronic chip has been developed
using $55~\mathrm{nm}$ CMOS technology for future electron-positron collider
experiments (namely Higgs factories). Extensive tests have been performed to
evaluate the timing performance of a dedicated SiPM-readout system equipped
with a PIST chip. The results show that the system timing resolution can
achieve $45~\mathrm{ps}$ for SiPM signals at the minimum-ionizing particles
(MIP) level ($200~\mathrm{p.e.}$) and better than $ 10~\mathrm{ps}$ for signals
larger than $1200~\mathrm{p.e.}$, while the PIST intrinsic timing resolution is
$4.76 \pm 0.60~\mathrm{ps}$. The PIST dynamic range has been further extended
using the time-over-threshold (ToT) technique, which can cover the SiPM
response spanning from $\mathrm{\sim 900~p.e.}$ to $~\mathrm{\sim 40000~p.e.}$.
