| Abstract | The increasing availability of commercial CMOS processes with high-resistivity wafers has fueled the R&D; of depleted monolithic active pixel sensors (DMAPS) for use in high energy physics experiments. One of these developments is a series of monolithic pixel detectors with column-drain readout architecture and small collection electrode allowing for low-power designs (TJ-Monopix). It is designed in a 180 nm TowerJazz CMOS process and features a pixel size of 33 $\mu$m $\times$ 33 $\mu$m. The efforts and improvements on the front-end electronics and sensor design of the current iteration TJ-Monopix2 increase the radiation hardness and efficiency while lowering the threshold and noise. |
