Quantum computing is one of the promising candidates to overcome the limitations of *classical* computing, e.g. von Neumann architecture. Nowadays much progress has been made on the implementation of scalable qubits. This work focuses on semiconductor qubits, which need operating temperatures near 0 K. Room temperature electronics for control and readout, which are limiting the bandwidth and the scalability due to parasitic elements and heat conduction, are still widely used. Some progress has been made to integrate the qubit control and readout in the direct vicinity of the qubit at cryogenic temperatures. Especially readout electronics still have a limited scalability because of circuit size and power consumption. This work tries to overcome those limitations by comparing different readout architectures and implement a multiplexed and integrated readout circuit with lower area and power consumption. This integrated circuit in a 22nm FD-SOI technology will be placed on top of scalable quantum computing architectures and therefore might be a crucial step on the way to a multi-million qubit quantum computer.
