Ⅰ. BASIC OP-AMP CIRCUITS
1. INTRO
For mechanical engineering students, Op-Amp might not be familiar. The purpose of this experiment is to understand the fundamentals of Op-Amp. Also we need to understand the gain which is essential concept in Op-Amp.
2. THEORY
- Op-Amp
Op-Amp is an abbreviation of operational amplifier. An op-amp is a DC-coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended output. An op-amp produces an output voltage that is typically hundreds of thousands of times larger than the voltage difference between its input terminals
Ideal Op-amp
Above figure shows Ideal Op-amp. There is no such thing as an ideal op amp, but present day op amps come so close to ideal that Ideal Op Amp analysis approaches actual analysis.
There are several assumptions to be Ideal Op-amp.
First, assume that the current flow into the input leads of the op amp is zero.
Second, the op amp gain is assumed to be infinite, hence it drives the output voltage to any value to satisfy the input conditions.
