请问如何仿真一个跨导运放的跨导啊

If the output of ota can be directly connected to its input (i.e. same DC), its gm can be known as R = 1/gm. Otherwise, configuring it as an integrator can also find its gm. Try it！

thank you very much

两种方法，一种如二楼兄弟所说
另一种比较麻烦，根据定义测跨到输出虚地，将输出断开，接上DC偏置保持输出的直流工作点，
然后扫描输入的DC电压

谢谢两位热心高人的指点，谢谢

输出接直流偏置，扫描输入直流电压，然后一除吗?
