High Voltage CMOS (HVCMOS) sensor is a proposed cost effective alternative to the existing hybrid sensors in ATLAS ITk pixel barrel for outer layers. To prove the feasibility of HVCMOS sensors in ATLAS experiment, a large area demonstrator chip is being designed. This work presents the design details of three HVCMOS sensor chips with an overview of the measurement results of ATLASpix1 which is the first large area (1 cm × 2 cm) prototype in 0.18μm process. •Architecture overview of three monolithic CMOS detector prototypes.•A novel readout scheme called Content Addressable Buffer readout is proposed.•The proposed readout scheme is proven to be working under laboratory tests.
