This work presents a collection of circuits to promote the development of a large-scale monolithic integrated quantum processor in 22 nm FDSOI CMOS technology. These circuits are: a feedback circuit for automatically biasing CMOS inverter-based circuits, an LC resonator for qubit readout reflectometry and a digitally-controlled oscillator (DCO) for generating qubit spin manipulation pulses. The auto-biasing feedback circuit exploits the backgate terminal in FDSOI transistors to optimally bias CMOS inverter-based circuits at cryogenic temperatures. The LC resonator uses a sub-minimum-sized transistor with 50 nm width to demonstrate the detection of capacitance changes as small as 20 aF in a reflectometry experiment, which is analogous to the detection of a quantum state measurement. The DCO uses the same 50 nm device to achieve a fine-grained frequency resolution of 1.77 MHz, which allows the oscillator to tune into the Larmor frequencies of a group of qubits. Altogether, these circuits can be used in the development of a new quantum computing architecture which places the qubit arrays together with their accompanying electronics.
