1) Looking into the source or drain- is it impedance or resistance ? I think it’s resistance because there are no capacitors in effect ( mid band). Is this correct ?
2) when we calculate the resistance looking into the source or drain, we use a test voltage source . Is this test voltage dc or ac ?
3) when we use test voltage source , we ground the independent voltage source and open the current sources. Then how is the transistor in saturation region when we calculate the resistance?
Thank you so much
