Quantum computers seem very promising in solving problems that are too large to be solved by classical computers that are available today. However, to generate reasonable amounts of computing power, many qubits will be required. Each of the qubits has to be individually controlled and needs to be kept at cryogenic temperatures. To allow for the scaling of the number of qubits, control electronics are being developed, that operate close to the qubits, at a temperature of 4 Kelvin. These control electronics require a voltage reference as well. In this thesis, several voltage references implemented in a commercial 40-nm CMOS process will be presented. The voltage references are designed for the temperature range from 4.2 K up to 400 K. As bipolar transistors are not suited for operation at cryogenic temperatures, the references are implemented using MOS devices. Architectures employing NMOS, PMOS and DTMOS as core device have been implemented.
