WebCurrent flowing originally from source to drain of the synchronous MOSFET, Q 2, ramps to zero, and the current in Q 1 increases to the inductor current level. Hence, the loop shaded in red and labeled “1” in Figure 1 is designated as the high-frequency switching power loop (or “hot” loop). In contrast, the current flowing in the inductor, L WebCurrent-biased Josephson junctions exhibit hysteretic transitions between dissipative and superconducting states as characterized by switching and retrapping currents. Here, we develop a theory for diode-like effects in the switching and retrapping currents of weakly-damped Josephson junctions. We find that while the diode-like behavior of ... WebMay 24, 2024 · After that, current grows significantly more slowly than exponentially. The reason: real diodes aren't ideal. Besides the behavior modeled by the Shockley diode equation, they have non-ideal behavior like resistance. At low currents this resistance isn't very significant, and the voltage-current relationship is approximately exponential. fit express via san marino
