Chapter 1_BJT

In voltage divider bias configuration, the stability of the Q-point is primarily determined by:

• The collector current
• The base current
• The voltage divider resistors
• The feedback resistor

The Q-point on the DC load line represents:

• The cutoff region of operation
• The saturation region of operation
• The operating point of the transistor
• The transition region between active and cutoff regions

What is the purpose of the voltage divider bias configuration?

• To provide a stable operating point
• To maximize power dissipation
• To minimize voltage gain
• To minimize the input resistance

Which of the following biasing techniques is also known as the emitter feedback bias?

• Fixed bias
• Self-bias
• Voltage divider bias
• Bias stabilization

In fixed bias configuration, the base current is usually provided by:

• A resistor connected in series with the base-emitter junction
• A resistor connected in parallel with the base-emitter junction
• A capacitor connected in series with the base-emitter junction
• A capacitor connected in parallel with the base-emitter junction

What is the purpose of transistor biasing?

• To ensure proper operation in the active region
• To minimize power dissipation
• To maximize voltage gain
• To stabilize the operating point
