Q. Can you explain Noninverting Amplifier?
It is called "noninverting" because there is no sign inversion. A typical circuit is shown in Figure. With a finite op-amp gain Ao,
Since the ideal op amp draws no current,
i1 = i2
Also, as seen from Figure,
v2 = vi
In equating Equations, one gets
which is the gain of an ideal voltage follower. The same result applies if R1 →∞ (i.e., open circuit) for any finite R2.
how does this circuit work and what are th electrical components in it do?
Q What do you mean by Direct coupling? In this method the a.c. output signal is fed directly to the next stage. No reactance is included in this coupling network. Special d.c.
