High-Voltage CMOS sensors are based on depleted active diodes as sensor elements. Every sensor element – pixel – is equipped with the readout electronics that performs various tasks, from signal amplification, zero suppression, address generation to time walk correction. High-Voltage CMOS sensors are an option for pixel- and strip layers of ATLAS high-luminosity upgrade. Several prototypes...

The talk will give an overview of the studies and status of
CMOS-based sensors research and development for ATLAS strip detector
upgrade.
CMOS sensor can provide higher granularity, costs less in sensor fabrication compared to conventional planar sensor.
Furthermore, CMOS-based sensors collect charge from thin depleted region,
and it has potential to be thinned down to 50um for...

We present a TCAD simulation study of the properties of HVCMOS sensors as a function of substrate resistivity, pixel topology and biasing scheme. The effect of these parameters on the timing and detection efficiency will be discussed.

We present a detailed characterization of the CCPDv2 and CCPDv4 CMOS sensors capacitively coupled to FEI4. We discuss the equalization procedure and the strategy for lowering the CCPD threshold, its temperature dependence and the intrinsic limits of the system.

We present the results of the characterization of CCPDV2 and CCPDv4 sensors, before and after irradiation, at the SPS using the FEI4 Telescope. The effects of bias, threshold and irradiation on the efficiency and timing properties of the CCPD family of sensors will be discussed.
