Re: how to calculate Cin and Cout of a inverter by simulatio
You can drive a ramp signal with gradient (dV/dt) to the input and probe the current (I) at the input. U can find the input capacitance using the equation I=C*(dV/dt).
The method can be used for output capacitance as well.
Re: how to calculate Cin and Cout of a inverter by simulatio
Thanks!!
the input pin capacitance in this way is ok
but for the output pin it dose not work, because the output node has its own voltage, when add a signal to it, some errors will come out.
could you have other method please?
