Recap: Vin R2 Voltage divider Vout = I R1 R1 = Vin R1 R1 + R2 Thevenin’s equivalent Rth Vth 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 Zc = 1/jZC ZL = jZL ZR = R I tan 1 §¨ © zL · z R ¸¹
