Cryogenic Comparator Characterization and Modeling for a Cryo-CMOS 7b 1-GSa/s SAR ADC

This paper reports the experimental characterization and modelling of a stand-Alone StrongARM comparator at both room temperature (RT) and cryogenic temperature (4.2 K). The observed 6-dB improvement in the comparator input noise at 4.2 K is attributed to the reduction of the thermal noise and to the suppressed shot noise in the MOS...

A 7-bit 1-GSa/s Cryo-CMOS ADC for Spin-Qubit Readout

Quantum computing offers exponential speed-up for problems that are computationally intractable with classical computing. However, quantum processors with thousands to millions of quantum bits (qubits) are needed. Room-temperature electronics are used to control and readout today's qubits operating at cryogenic temperature. As the number of...
