Abstract: This experiment is intended to introduce the basic concepts of the operational amplifiers and to help us better understand the relationship between the resistances and the amplifier gain.
The main experiment focused on op-amps of which we have two types, inverting and non-inverting. With the inverting op-amps there is no current entering the amplifier terminals due to the infinite impedance of the amplifier so I1=I2 =0. The inverting amplifier uses negative feedback to invert and amplify a voltage by a certain gain value which is determined by the values of the input and feedback impedances. We will show this relationship in this experiment by changing the resistance values and measuring the voltages.
Introduction:
The purpose for this experiment is to get familiar with basic properties and applications of the integrated-circuit operational amplifier, the op amp, one of the most versatile building blocks currently available to electronic-circuit designers. The emphasis will be primarily on the nearly ideal, on what is easily and conveniently done. Exploration of what is less-than-ideal about commercial operational amplifiers will be deferred to later experiments. For the procedure the goal of this experiment is to design two different types of op amp circuits, one inverting and non-inverting op-amps. By using ( NI Elvis Unit, PC w/Multisim, Resistors, Capacitors, 741 Type Op Amp) to build op-amps.
