Multiple choice

If the base width in a bipolar junction transistor is doubled, which of the following statements will be TRUE?

  1. Current gain will increase.

  2. Unity gain frequency will increase.

  3. Emitter-base junction capacitance will increase.

  4. Early voltage will increase.

D Correct answer
Explanation

On increasing the base width, slope of the IC vs. VCE curve decreases due to less (IC). Hence, decrease in slope means increase in early effect. So, early voltage will increase.
