D) two power supplies.

Question

Quizplus · Accepted Answer

The voltage gain of an operational amplifier with an open-loop configuration is given by the ratio of the output voltage to the input voltage, and it can be adjusted by using two external resistors. The gain (Av) is given by Av = -Rf/Rin,where Rf is the feedback resistance and Rin is the input resistance. The bandwidth of the operational amplifier can be adjusted by selecting the appropriate feedback configuration and external components, such as capacitors or resistors, to achieve the desired frequency response. However, the most basic method of adjusting the voltage gain and bandwidth of an operational amplifier is by using two external resistors.
