pss仿真问题

偶然间看到一个仿VCO的资料里有个pss仿真中出现了transconductance,小弟最近在仿跨导放大器中GM随输入电压变化的曲线，不知道应该如何由Cadence中控件直接得到，而不用借助于计算器，请多多指教

不知道

扫描行不?

路过看看

You may use parametric analysis in Cadence ADE, use the input DC voltage as the sweeping parameter. At each sweeping point, do a AC analysis at 0Hz. You need to tie the output to a DC voltage source. Measure the AC current in the voltage source.

有没有人做过PSS仿真?同求解
