Vin
Vout = I R1
R2
R1= Vin
R1 + R2
R1
Recap:
Voltage divider
Vth
Rth
Thevenin’s equivalent
Rload
How to avoid voltage droop?
To appear in Quiz
Method 1: apply kirchoff’s law
Method 2: use Rth = Vth/Is
Is is the short circuit current.
When we short the output to ground,
what is the current through R4?
Q = CV
I = C dV/dt
