“If you identify an input source, the transfer function and the
input-referred noise for an equivalent noise-free network is computed.”这是Cadence circuit simulator reference中的原话。我现在画了一个简单的原理图,有输入输出端口,仿真过后direct plot->main form的function栏有一个“transfer function”,点击它做出一条曲线,曲线title是“pnoise gain” 我想请问这个pnoise gain是怎么计算 的,和电路的增益是一回事吗?
