论文摘要
Quantum computing (QC) requires cryogenic electronic circuits as control and readout sub-systems of quantum chips to meet the qubit scale-up challenges.At this temperature,MOSFETs transistors exhibition many changes such as higher threshold voltage,higher mobility,and steeper substhreshold slope.We present a cryogenic fully differential gain boosting-OTA used for a 14 bit Pipelined-SAR ADC operating at 4.2K as the readout基于半导体的量子计算系统的电路。使用$ g_ {m}/i_ {d} $方法论，以基于低温110nm bsim4型号获得预计的查找表在闭环应用程序中，$ f _ {-3db} $的$ f _ { - 3db} $好于0.01 \％。
