In the single-stage transistor amplifier circuit shown in the given figure, if capacitor CE is removed, then, ac small-signal midband voltage gain of the amplifier
-
- increases
- decreases
- is unaffected
- drops to zero
Correct Option: B
With CE, voltage gain
Aυ = - | ||
hie + (1 + hfe)RE |
If RE by passed with capacitor CE, AV will increase Hence, after removing CE mid band voltage gain decreases.
