In LTSpice, including the mirror decreased the enter referred noise, and it did not show an important contribution from All those transistors. Having said that, I am far more assured within the accuracy (and relevance) of my measurements than I am of your simulation outcomes. ）是射频接收系统的核心器件，用于放大微弱信号并最小化噪声引入，其参数直接决定系统灵敏度、动态范围和信号质量。通... https://beckettcuisf.targetblogs.com/34669037/the-smart-trick-of-pin-diode-switch-that-nobody-is-discussing
