Weeroc analogue and mixed‑signal ASIC chips are highly integrated front‑end readout solutions designed for a wide range of photon and particle detectors, including SiPMs, PMTs, MA‑PMTs, PIN diodes, and gaseous detectors. They feature programmable architectures, low‑noise performance, and high precision in both time and energy measurements, enabling accurate and reliable signal processing.

These ASICs support self‑triggering capabilities and flexible readout configurations, ensuring fast and efficient integration into complex acquisition systems.

Weeroc designs and produces front-end ASICs for the readout of most commonly used particle detectors, suitable for a wide range of applications. Main customers are the major actors in the fields of:

Medical imaging
Homeland security
Nuclear protection
Scientific instrumentation
Space (launchers and satellites)
