Thank you for your help .
So does it mean when Q2 is cut off, there is no current pass thru Q13 to Q4 and then to Q5?
For current at Q12, I am just wondering why not Id12= Id11+Ibias? How do we know Id11 is greater than any of Id12 and I bias?
Looking at the configuration of Q11, Q12, Q3 comparing with Q11, Q13, Q4, I think the configuration is exactly the same. But why the current relation is different with
Q11-Q13-Q4: Id4=Id11(why not similar like Id11 with Id4=Id13+Ibias)?
Can you help me on this?
regards and thanks
