Given below is a differential amplifier in which V1=V2. What happens to VOIB at this condition?
A. VOIB= 0
B. VOIB= VOIB×10-10
C. VOIB= VOIB/2
D. VOIB= -1
Answer:A
Given below is a differential amplifier in which V1=V2. What happens to VOIB at this condition?
A. VOIB= 0 B. VOIB= VOIB×10-10 C. VOIB= VOIB/2 D. VOIB= -1
Explanation: The voltage V1 and V2 are caused by the current IB1 and IB2. Although this bias current are very small, if they are made equal, then there will be no output voltage VOIB.
