The CMS MIP Timing Detector, proposed for the HL-LHC upgrade, will be instrumented with O(10) square meters of ultra-fast Silicon detectors (UFSD) in the forward region. These UFSDs are aimed at measuring the time of passage of each track with a precision of about 30 ps. The sensor that will be used for this task is the low gain avalanche detectors (LGAD). In this contri- bution, we will present the latest results from laboratory measurements on 50 and 35 μm thick LGADs fabricated by CNM, in the framework of the AIDA-2020 project. We will concentrate on the timing performance of the sensors. Additionally the electrical characterisation of the sensor will be discussed.
