The upcoming High-Luminosity upgrade of the Large Hadron Collider (HL-LHC) will dramatically increase event pile-up, demanding new 4D tracking capabilities with high-precision timing to resolve particle tracks. While Low-Gain Avalanche Diodes (LGADs) offer excellent time resolution, their complex manufacturing and costly bump-bonding assembly present significant challenges. This talk explores Depleted Monolithic Active Pixel Sensors (DMAPS) as a promising, cost-effective alternative that integrates the sensor and readout electronics on a single substrate. We will focus on the measurements carried out at IFAE on the MiniCACTUS-V2 prototype, a DMAPS device designed partially by IFAE for fast timing applications within the context of the ATLAS experiment.
