论文摘要
我们建议使用有限的冷却预算的应用,尤其是太空观测值中的探测器阵列读数,提高了功率效率的鱿鱼放大器配置。建议的两台配置在输入的半个周期期间将一个鱿鱼保持在零电压状态,而另一鱿鱼会产生电压。对于其他半循环,鱿鱼的角色是逆转的。该电路是在B类中运行的基于晶体管的放大器的静电双重。提出了在t = 4.2 K处的原理证明。
We suggest a SQUID amplifier configuration with improved power efficiency, for applications where cooling budgets are limited, in particular superconducting detector array readouts in space observatories. The suggested two-SQUID configuration keeps one SQUID in a zero-voltage state during a half-cycle of the input while the other SQUID generates voltage. For the other half-cycle the roles of the SQUIDs are reversed. The circuit is an electrostatic dual of a transistor-based amplifier operating in class-B. A proof-of principle demonstration at T = 4.2 K is presented.
