Timing performance of radiation hard MALTA monolithic pixel sensors

The MALTA family of Depleted Monolithic Active Pixel Sensor (DMAPS) produced in Tower 180 nm CMOS technology targets radiation hard applications for the HL-LHC and beyond. Several process modifications front-end improvements have resulted hardness up to $2 \times 10^{15}~1~\text{MeV}~\text{n}_{eq}/\text{cm}^2$ time resolution below 2 ns, with uniform charge collection efficiency across size $36.4 36.4~\mu\text{m}^2$ a $3~\mu\text{m}^2$ electrode size. MALTA2 demonstrator 2021 on high-resistivity epitaxial silicon Czochralski substrates implements new cascoded that reduces RTS noise has higher gain. This contribution shows results from timing at nanosecond level CERN SPS test-beam campaign 2021.
