Transfer characteristic [output voltage (V₀ )v s input voltage . (V_i ) ] for a base biased transistor in CE configuration is as shown in the figure. For using transistor as a switch, it is used

Options

  1. Ain region III
  2. Bboth in region (I) and (III)
  3. Cin region II
  4. Din region I

Correct answer

B. both in region (I) and (III)

Step-by-step solution

In the given graph, Region (l) Cutoff region Region (II) - Active region Region (III)-Saturation region Using transistor as a switch it is used in cutoff region or saturation region. Using transistor as a amplifier it is used in active region.
