Re: Can I get the output impedance of OPAMP by hspice simula
Hi,
There is nothing to do with code. If you see into the output listing file .ls then you will be probably find out the value of output resistance. Value of input and output resistance will be given probably.
If I am wrong then please let me know. Because I am not in touch of these thing now a days.
Thanks!
I have read the file which you attach, form this file, I think it may be use ".print AC Zout(M)" to simulate output impedance, but if that so, I have two questions:
1. I didn't write output node, how does it know which node is the Zout.
2. How to add the AC source, add it to the input? or VCC?
Hi, everybody
Thanks for your advice, as to the TF command, i tried to use it and got a zero value, I guess what TF does is that at every DC point, it measures the DC voltage and DC current , and then compute the DC output impedance..
