Question

***PERFORM IN MULTISIM OR I WILL THUMBS DOWN

C. DESIGN PROBLEM - X10 AMPLIFIER Choosing the appropriate one of the two circuits above, design an amplifier that has a voltage amplification factor of +10 (i.e., the output signal should be 10 times larger than the input signal, and also be in-phase with the input signal). You may use any values for your resistors, but avoid values greater than 100k2. 12.

Answer 1

for non-inverting amplifier

R2 Gain = 1+ =10

R2 = 10-1=9 RI

Let R2=10k

R210k R1 = = 1.122
