The shift in level is given as VI – VO = VBE + I×R1 =0.07v+1.19mA×5kΩ =6.65v. 10. Load resistors (Re) is neglected for maximizing the voltage gain in amplifier because,
A. Requires large chip are
B. Requires large power supply
C. Quiescent drop across Re increases
D. All of the mentioned
Answer:A
The shift in level is given as VI – VO = VBE + I×R1 =0.07v+1.19mA×5kΩ =6.65v. 10. Load resistors (Re) is neglected for maximizing the voltage gain in amplifier because,
A. Requires large chip are B. Requires large power supply C. Quiescent drop across Re increases D. All of the mentioned
Explanation: As gain is proportional to load resistor, large resistance value is required. Due to limitation mentioned, it is neglected. 11. What is the need for level shifter in operational amplifier?
