What is the difference of meaning between the phase angle of S11 and the phase angle of Γ (Gamma)?
I realized recently that the Touchstone "DB" S-parameter format (.s1p, etc) uses the phase angle of \$\angle \Gamma\$ instead of \$\angle S_{11}\$ and wondered why it didn't use the phase ...

Load impedance seen by op-amp
I have a question about the load impedance seen by an ideal op-amp output terminal in inverting configuration.
When calculating the load impedance, we set Vin = 0;
In one way I could say that the ...
