001046654 520__ $$aIn view of the post-Moore’s law era, new computational paradigms that could serve as powerful alternatives to the classical computing are under development. One of those paradigms is Quantum Computing (QC). By using the quantum mechanical properties of superposition and entanglement via the manipulation of a large number of qubits, QC systems promise to speed up the finding of solutions to the computational challenges faced in cryptography, optimization of different processes, and quantum systems simulation. These applications position the QC systems as powerful tools for humanity. However, the design, assembly, deployment and operation of a QC system are not simple tasks. This is because QC devices, such as superconductive qubits or semiconductor quantum dots, require an ambient temperature lower than 100mK in order to reduce the influence of heat sources that could disrupt the qubits state information and coherence. Also, the only practical way in which a QC device can be subjected to such low temperatures is by means of a dilution refrigerator, a complex machine with limited room for Devices Under Test (DUTs), electrical connections for DC and RF signals, and cooling power. In order to increase the QC system performance, such a system must be composed by a high number of fault-tolerant qubits. As well as by hardware and software capable of enabling its scalability. Moreover, it is expected that by incorporating cryogenic CMOS ICs as part of QC systems, the number of connections between the qubits and the Room Temperature (RT) electronics will be reduced, relaxing the dilution refrigerator requirementsand allowing the system scalability. In addition, the signal integrity of the signals controlling the qubits could be improved by the shorter interface with the local cryogenic electronics based on ICs. But the most important advantage offered by CMOS IC technology is its potential integration with qubit devices. In particular, the semiconductor gate defined quantum dot, a device that stores and controls an electron operating as qubit. Thus, the development of analog, digital, and mixed-signal cryogenic CMOS ICs has attracted significant attention in the last years. As it has been demonstrated that IC technology can be an important part and key enabler of the QC systems scalability. This work contributes to cryogenic analog MOS circuit design discipline through the development, integration and test of a cryogenic Power Management Unit (PMU) composed by a CMOS IC and additional passive components. The cryogenic PMU is developed with a 22 nm FDSOI technology, as it supplies MOSFETs that can operate at Cryogenic Temperatures (CTs) without significant performance degradation. Ultimately, the goal is to provide a regulated and lownoise voltage supply to other circuit blocks located at CT environments close to 4 K, reducing the amount of DC connections between the RT equipment and the cryogenic electronics. Hence, the QC systems scalability effortsare thereby supported.
