Hi!
Here is my task:
a) Calculate and sketch Iout=f(Vc2), for 0<Vc2<1.5V. (neglect Early effect)
b) calculate output resistance for Vc2=Vc1.
BJT's Q1 and Q2 are in forward active mode, have identical characteristics and same temperature. MOSFET M3 is in saturation. Iin=10μA, Vt=25mV, Vc1=1.25V, VA=50V.
My question is, what does VDD represent? There are few examples in my book where VDD is connected to some current source like this...
