Description

High Voltage Monolithic Active Pixel Sensors (HVMAPS) are based on
a commercial High Voltage CMOS process and collect charge by drift
inside a reversely biased diode. HVMAPS represent a promising technology for
future pixel tracking detectors.

Two recent developments are presented. The Mupix has a continuous readout and
was developed for the Mu3e experiment whereas the ATLASpix has a triggered
readout and was developed for ATLAS. Both variants have a fully
monolithic design including state machines, clock circuits and serial
drivers. Several prototypes and design variants were characterized in the lab
and in testbeam campaigns to measure efficiencies, noise, time resolution and
radiation tolerance.
Results from recent Mupix and ATLASpix prototypes are presented and prospects
for future improvements are discussed.
