Explanation: Because of direct couple, Dc level rises stages to stage and tends to shift operating point. This limits output swing (Voltage). 12. Limitation of an output stage amplifier, if it emitter follower with complementary transistor
A. Cross-over distortion
B. Low impedance output
C. Shift in level
D. Active load current
Answer:A
Explanation: Because of direct couple, Dc level rises stages to stage and tends to shift operating point. This limits output swing (Voltage). 12. Limitation of an output stage amplifier, if it emitter follower with complementary transistor
A. Cross-over distortion B. Low impedance output C. Shift in level D. Active load current
Explanation:The limitation in the amplifier is that , the output voltage remains zero until the input voltage exceeds cut in voltage VBE= 0.5v, which is known as cross-over distortion. 13. An output stage amplifier can produce output signal, when the input signal is
