## Abstract

We present the numerical proof of a new sensor concept, based on the Resistive AC-Coupled Silicon Detectors (RSDs) paradigm and standard CMOS process, which benefits from having a 100% fill factor and embedded front-end electronics. The compatibility between these two technologies has been investigated, and our encouraging results suggest that this target could be reliably achieved, enabling the possibility to considerably boost the performance of current silicon detectors intended for timing and 4D-tracking.
