The ATLAS experiment will start operating at the High Luminosity LHC accelerator (HL-LHC) in 2026 to increase the probability of new discoveries. Depleted CMOS monolithic pixel detector technology has been one of the options considered for the outer layer of an upgraded ATLAS pixel detector and is a high potential technology for future pixel detectors. In this thesis, several prototypes have been developed using different depleted CMOS technologies, for instance, LFoundry (LF) 150 nm, TowerJazz (TJ) 180 nm and austriamicrosystems AG (AMS) 180 nm. In a high-energy environment like HL-LHC, Single Event Upsets (SEU), which become of concern for reliable circuit operation. Several test-chips in AMS, TowerJazz and LFoundry technologies with different SEU tolerant structures have been prototyped and tested. The SEU tolerant structures were designed with appropriate electronics simulations using Computer Aided Design (CAD) tools in order to study the sensitivity of injected charge to upset a memory state. An alternative powering scheme named Serial Powering scheme is foreseen for the future Inner Tracker (ITk) detector of the ATLAS experiment. To meet the requirements ofthe ATLAS experiment to the environment of a pixelated layer in a high radiation collider environment, new developments with depleted CMOS sensors have been made in Shunt-LDO regulator and sensor biasing which are designed in modified TowerJazz 180 nm CMOS imaging technology. In the TowerJazz modified process, two different voltage levels are used for the purpose of sensor depletion. The bias voltages are generated by using a negative charge pump circuit.

The Inner Tracker (ITk) system of the ATLAS experiment will be upgraded for the 2026 High Luminosity Large Hadron Collider (HL-LHC) run. The HL-LHC will operate with a center of mass energy of 14 TeV and a peak instantaneous luminosity five times higher than at present. The increased luminosity will result in roughly ten times higher radiation levels and data rates. To cope with the ATLAS requirements in terms of radiation hardness, readout speed and granularity at the HL-LHC, the replacement of the present ATLAS Inner Tracker (ITk) is needed. Two large-scale depleted CMOS sensors in the 150 nm LF-technology called LF-CPIX and LF-MONOPIX, developed in the framework of the ATLAS Inner Tracker (ITK) upgrade for High Luminosity LHC. The work presented here shows the characterization for these three prototypes, with contributions concerning the setup development, 55Fe and 90Sr source calibration, modifications of the FPGA firmware and development of test programs. A main concern was the investigation on the radiation hardness for both the electronics and the sensor parts. We will show results concerning characterizations for these prototypes in the laboratory performance at CPPM, as well as results in multiple radiation campaigns performed at the 24 GeV IRRAD proton facility at CERN, to study the effects of Non-Ionizing Energy Loss (NIEL) and Total Ionizing Dose (TID) on the prototypes.

What are the elementary particles and how did the universe originate are the main driving forces in the high energy physics. In order to further demonstrate the standard model and discover new physics, several detectors are built for the high energy physics experiments. CMOS pixel sensors (CPS) can achieve an attractive tradeoff among many performance parameters, such as readout speed, granularity, material budget, power dissipation, radiation tolerance and integrating readout circuitry on the same substrate, compared with the hybrid pixel sensors and charge coupled devices. Thus, the CPS is a good candidate for tracking the charged particles in vertex detectors and beam telescopes.The power distribution becomes an important issue in the future detectors, since a considerable amount of sensors will be installed. Unfortunately, the independent powering has been proved to fail. In order to solve the power distribution challenges and to provide noiseless voltages, this thesis focuses on the design of a low noise, limited area, low power consumption and full on-chip power management in CPS chips. The CPS are firstly introduced drawing the design requirements of the power management. The power distribution dedicated to CPS chips is then proposed, in which the power management is utilized as the second power conversion stage. Two full on-chip regulators are proposed to generate the analog power supply voltage and the reference voltage required by correlated double sampling operation, respectively. Two prototypes have verified these regulators. They can meet the requirements of CPS. Moreover, the power management techniques and the radiation tolerance design are also presented in this thesis.

Das ATLAS Experiment ist eines von vier großen Experimenten am LHC. Der LHC ist der größte Teilchenbeschleuniger am CERN, dem europäischen Kernforschungszentrum. Bei den Experimenten im LHC kollidieren zwei Teilchen-Strahlen mit Geschwindigkeiten nahe der Lichtgeschwindigkeit. Eine Kollision wird dabei als Event bezeichnet. Um ein möglichst umfassendes Bild von diesen Events zu bekommen und von den Teilchen, die dabei entstehen, ist der ATLAS Detektor in mehreren Schichten aufgebaut. Die innersten Schichten sind mit Pixel Sensoren ausgekleidet. Da diese am nächsten zum Kollisionspunkt sind, ist der Schaden durch radioaktive Strahlung bei diesen Modulen am höchsten. Da die Strahlung mit dem kommenden Upgrade des LHC, dem HL-LHC, zunimmt, müssen auch die verwendeten Module widerstandsfähiger gegenüber Strahlung werden. Neben der höheren Strahlung wird auch die Eventrate steigen, was ein schnelleres Auslesen der Pixel-Module erfordert. Zusätzlich steigt auch die geforderte Auflösung für die einzelnen Experimente. Zu diesem Zweck wird eine neue Schicht der Pixel Detektoren eingebaut. Da mit größerem Radius auch die auszukleidende Fläche steigt, werden sehr viele Module benötigt. Um die Kosten gering zu halten wird ein Standard-CMOS-Prozess bevorzugt. Diese Prozesse sind weit verbreitet, können in großer Stückzahl und relativ kostengünstig gefertigt werden. Das jüngste Projekt um einen Pixel Detektor in einem dieser Prozesse umzusetzen, ist der MiniMALTA3 Chip. Diese Arbeit präsentiert ein digitales Modul, welches in diesem Chip verwendet wird. Dieses Modul heißt Fast Command Encoder und wird verwendet um andere Module in deren Ausgangszustand zurückzusetzen. Neben dem Zurücksetzen wird dieser Block auch verwendet um den Threshold der aktiven Pixel über TS-Scans einzustellen. Da dieser Thresehold von vielen Parametern abhängt, welche alle individuell untersucht werden müssen, sind viele TS-Scans notwendig. Um die Gesamtdauer der Adjustierung gering zu halten, muss die Zeit eines einzelnen TS-Scans reduziert werden. Der Fast Command Encoder wird durch ein 320 MHz Signal getaktet, was bedeutet, dass TS-Scans mehr als 32 schneller ausgeführt werden können als in den vorherigen Generationen. Das digitale Design für dieses Modul wird zusammen mit den Parametern für die Synthese vorgestellt. Die einzelnen Schritte werden durch Simulation verifiziert und die gewünschte Funktionsweise sichergestellt.
