abstract = {In 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.},
