论文摘要
我们设计并制造了一个集成的两阶段鱿鱼放大器，只需要一条偏置线和一条磁通设定点线。从偏置的角度来看，两个阶段是串联连接的，而从信号传播角度来看，阶段是级联的。提出了在t = 4.2 K处的原理证明。
We have designed and fabricated an integrated two-stage SQUID amplifier, requiring only one bias line and one flux setpoint line. From the biasing viewpoint the two stages are connected in series while from the signal propagation viewpoint the stages are cascaded. A proof-of principle demonstration at T = 4.2 K is presented.
