A 90-Nanometer DAC Kept Tuning in the Cold
The programmable current source controlled pulse amplitude and slopes while driving a superconducting circuit.
Summary
The programmable current source controlled pulse amplitude and slopes while driving a superconducting circuit.
A planar 90-nanometer CMOS current DAC operated at cryogenic temperature with digital control over amplitude and rise and fall slopes, plus externally triggered pulse width. Tests closely matched circuit predictions, supporting a more flexible control component for superconducting-qubit and readout hardware.
