AB  - In most quantum experiments nowadays the control and readout electronics is placed at room temperature. The number of qubits which can be operated with this approach is severely limited by the number of interconnects and the wiring between the qubit operating temperature level and  the  room  temperature  level.  At  the  Central  Institute  for  Electronic  Systems  at  the Forschungszentrum Jülich we develop and design scalable solutions for readout and control of qubits for future use in quantum computers. Our approach leverages the advances of state-of-the-art  commercial  CMOS  technologies  while  operating  at  deep-cryogenic  temperatures close to the actual qubit. We designed and layouted a first chip for concept proof in a commercial 65 nm CMOS process. This chip contains a DC-digital-to-analog converter (DC-DAC), a pulse digital-to-analog converter, a 500 MHz digitally controlled current starved ring  oscillator  and  a  20 GHz  LC-oscillator.  The  DC-DAC  is  operating  in  a  voltage  range between 0 V and 1 V. The pulse DAC operates at a sample rate of 250 MHz and generates pulses in a range of 8 mV. In this presentation the chip architecture will be discussed in detail and corresponding simulation results will be shown.
