in gains of 10 50 100 I The circuit shown in Figure 62 is a

in gains of 10, 50, 100 I. The circuit shown in Figure 6.2 is a follower with gain. To obtain gains of 10, 50, 100, what are the values of R,?

Solution

Given circuit is noninverting amplifier circuit.

Gain of the noninverting amplifier circuit=1+(Rf/R0)

1) To obtain gain 10:

1+(Rf/R0)=10

Rf=9*R0=9*1K=9K

2)

To obtain gain 50:

1+(Rf/R0)=50

Rf=49*R0=49*1K=49K

3) To obtain gain 100:

1+(Rf/R0)=100

Rf=99*R0=99*1K=99K
