Operational Amplifiers - Technical MCQs
Q1:
 Decreasing the gain in the given circuit could be achieved byA reducing the amplitude of the input voltage
B increasing the value of the feedback resistor
C increasing the value of the input resistor
D removing the feedback resistor
ANS:C - increasing the value of the input resistor Acctually the diagram is in inverting configuration. So it has gain equation Gain= -Rf/Rin. It means gain inversly proportional to Rin. Therefore answer is C. Share : |
