电路图长这样，然后仿真出现错误
ERROR (SPECTRE-16385): There were 8 attempts to find the DC solution. In some of those attempts, a signal exceeded the blowup limit of its quantity. The last signal that failed is V(NM2:int_d) = 3.01693 GV, for which the quantity is `V' and the blowup limit is (1 GV). It is possible that the circuit has no DC solution. If you really want signals this large, set the `blowup' parameter of this quantity to a larger value.
ERROR (SPECTRE-16080): No DC solution found (no convergence).

我觉得是电流源的原因，但是不知道为什么
这个原理图是跟着别人弄的，他们就是这样就能成功，我的就不行
