为什么差分电路不能收敛？
录入：edatop.com 阅读：
在ADS里面仿真差分PA不能收敛，出现如下错误：Error detected by hpeesofsim during HB analysis `HB1'.
No convergence.
Error detected by hpeesofsim during HB analysis `HB1'.
Divergence in the KCL check detected.
Convergence hints:
o Double the fundamental oversample.
o Select the direct solver.
o Set Matrix Re-use to Robust.
o Select the Krylov solver.
o Increase Krylov Restart Length to 150.
This is the maximum value based on available memory.
o Try TAHB (transient assisted HB).
o Select the Robust convergence mode,
o Increase max. iterations to 1000.
o Increase the order.
o Try to sweep a parameter.
o Decrease MaxStepRatio.
而单端PA在输入功率范围为-25dBm～10dBm都可以收敛！
差分PA在输入功率小于-5dBm可以收敛，超过之后就会报错！
求大神解释！
春节快乐！
