4. 4
DC Operating Point (Q-Point)
• Dc Bias
• Establishes the DC operating point (Q-point) for proper
linear operation
• Otherwise will go in saturation or cutoff

5. 5
DC Bias

6. 6
DC Bias
Ic = β IB
VCE = Vcc – IC RC

7. 7
DC load line

8. 8
Voltage Divider Bias
• I2 >> IB (Stiff Voltage Divider)
