The Belle II collaboration has initiated a program to upgrade its detector in order to address the challenges set by the increase of the SuperKEKB collider luminosity, targeting 6x1035 cm2 s-1. A monolithic CMOS pixel sensor named OBELIX (Optimized BELle II pIXel) is proposed to equip 5 detection layers upgrading the current vertex detector. Based on the existing TJ-Monopix2, OBELIX is currently designed in 180 nm CMOS process.
