Hi, all,
I'm using the TSMC 0.13um CMOS proccess. I would expect some influence to the frequency response, for example for one amplifier stage, when I was using a huge resistor as the AC coupling bias resistor for the next stage. But the simulation results show almost no influence, and I found that the resistor, for example rphpoly, has no parasitic capacitance in the equivalent circuit in the model file.
So my question is how can I get the practical performance of the circuit, when these components' model didn't provide parasitics in the model file?
