본문내용
In this chapter, our goal is to understand the concept of an op-amp and its circuits, such as inverting amplifier, noninverting amplifier, adder, subtractor, differentiator, and integrator. Then, we will design the op-amp circuits and circuits with Wheatstone Bridge using PSPICE simulation.
Theory
Operational Amplifier
An op-amp is supposed to sense the difference between the voltage signals applied at its tow differential inputs, v_p-v_n. By multiplying v_p-v_n by a number A_v(open-loop voltage gain), A_v (v_p-v_n) is appeared at the output terminal. The real op-amp has a very large gain, A_v, but not infinite.
v_o=A_v (v_p-v_n )=A_v v_id
The differential transfer characteristic v_0 versus v_p-v_n of the basic op-amp and diagram are shown in [Figure 1-1], [Figure 1-2], respectively. In the linear region, v_o=A_v (v_p-v_n ). For positive saturation region, v_0=V_CC for A_v v_id>V_CC. For negative saturation region, v_0=〖-V〗_CC for A_v v_id<-V_CC.
