Enhancing Equivalent Circuit Simulation of Intrinsic Josephson Junction Stacks Using Modularization of LTspice Elements
Abstract
We have developed a construction method of equivalent circuits for an intrinsic Josephson junction stack using the modularization feature in LTspice. This method improves the readability of circuit diagrams in circuit simulations of terahertz-radiating Josephson plasma emitters and enhances scalability, such as modifying the number of coherently oscillating junctions. These improvements enable easier simulation of complex models and parameter sweeps, contributing to device optimization for practical THz emitters.
