The proof-of-concept of a monolithic silicon pixel detector in SiGe Bi-CMOS technology for outstanding tracking and timing performance was produced in the SG13G2 process of IHP Mikroelektronik. Measurements with a 90Sr source show a time resolution of 50ps for hexagonal pixels of 130µm side. The performance of the front-end electronics is compatible with Cadence Spectre simulations and shows the potential of this technology to be used in future tracking detectors with precise 4D measurement capability.
