Abstract: A scalable eight channel DAC designed in a TSMC 65-nm CMOS technology for generation of solid-state quantum bit (qubit) bias voltages is presented. Measurement results of the DAC and some additional auxiliary components like an on-chip amplifier and sigma-delta modulator at 6 K are discussed. With a low-power consumption of 2.7 μW per channel, the DAC fulfills the requirements to be placed next to qubits inside a mixing chamber of a dilution refrigerator, showing a promising way for scaling qubit numbers toward a quantum computer.
