The general-purpose circuit simulator analysis program for linear active circuits (APLAC) is not widely known within the superconductor circuit community, regardless of its built-in Josephson junction model and capability of modeling the superconductive phase transition with controlled sources. We review the use of APLAC to model, e.g., noisy dc SQUIDs and transition-edge sensors. Based on an APLAC simulation, we also comment on the preference of voltage bias over current bias in dc SQUIDs in applications where large dynamic range and high bandwidth are simultaneously required.

超导电路和通用电子模拟器APLAC

线性有源电路的通用电路仿真器分析程序（APLAC）在超导体电路领域并不广为人知，无论其内置的约瑟夫森结模型和使用受控源建模超导相变的能力如何。我们回顾了使用APLAC建模的方法，例如，噪声直流SQUID和过渡边缘传感器。基于APLAC仿真，我们还评论了在同时需要大动态范围和高带宽的应用中，直流SQUID中电压偏置相对于电流偏置的偏爱。
