Emitter Bias with Two Supplies The schematic diagram is shown in Figure (a). figure (a) Emitter bias with two supplies In base emitter circuit, it can be written by KVL, -IBRB -VBE - IERE+VEE= O
If VEE>> VBE and RE>>RB/β, Eq. (1) can be written as: Stable Q-point can be obtained by using this method because two supplies (positive and negative). IC is independent of β. | |
