Question

I sent you this project. The content was good but it was too short and it was by handwritting. can you do it again for me but with more information please. because the report should be 4-5 pages and circuites should not be handwritting. I really appreciate it.

Student name: Student ID: Note: Please, answers must be on this word file, write your name, year ID, then write your answer with all figures and screen shots and comment on these screen shots in this word file, when you finish save file as PDF then email it to me, Name the file (your name-Project1), late response will not acceptable. Pages of project must be 4 to 5 pages. Project 1 (20 Marks) Project on Electronic Device The project on electronic device will be according to your first digit in your student as following: First digit in your 0 or 1 2 or 4 5 or 7 849 ID Device Diode BJT OP-AMP Tranor mer For example if your ID is 120218035, so the first imber is nothwede ice will be OP-AMP. Note: this report must include additional information noudede lectures, any information from lectures not acceptable, and any similarity between students' reports not acceptable also. Project most includes: 1. Define the device including theoretical principle of operation. 2- One circuit application of this device in details. 3. Simulate this circuit application using simulator and discuss the results of simulation.

Answer 1

An Operational Amplifier, in short popular as an op-amp, is an active amplifying device designed mainly to amplify voltages and be used with external feedback components like resistors and capacitors between its input and output terminals. It is generally an electronic voltage amplifier with high-gain along with a differential input and generally consists of a single-ended output. Among all the amplifier mechanisms, the op-amp is the most widely used one.

Op-amp operation

The op-amp's differential inputs consist of an inverting input and a non-inverting input and. Ideally, an op-amp can amplify only the differential voltage between the two input terminal. The output of the op-amp can be calculated as (without any feedback):

Vout = AOL(V+ V-)

AOL is open-loop gain of the op-amp. In an op-amp, the output is the amplified version of the input, which is dependent on the op-amp characteristics. The two fundamental concepts, associated with the op-amp are, it has an infinite input impedance, ( Zin = ∞ ) That allows no current to flow into the op-amp through the input terminals and a zero offset voltage V1 = V2. An op-amp also provides zero output impedance, ( Zout = 0 ). Ideally, an op-amp also provides Infinite open-loop voltage gain Ao, in infinite bandwidth providing a zero degree shift in phase and also an infinite slew rate.

Here are some important amplifier configurations using op-amp:

Voltage Follower

This is the most basic configuration of the op-amp, also known as a voltage buffer. No external components are required for this configuration. The output voltage is simply the input voltage.

This circuit provides a very high input impedance with a low output impedance. This configuration is useful in the case of interfacing logic levels between two devices or when the power supply is based on the voltage divider circuit.

Inverting Op-amp

Where R2 is the feedback resistor and R1 is the input resistor. An inverting op-amp produces output amplifying with a negative finite gain so the polarity of the output is just opposite to the input. Usually, the positive terminal of the op-amp is grounded.

Non-inverting Op-amp:

This configuration is very similar to the inverting one but the only difference is the input voltage is directly applied to the positive input and the negative terminal is grounded being connected with the input and the feedback resistors.

Differential op-amp

This op-amp configuration calculates the difference between the voltage levels of the two input terminals and amplifies it with some finite gain.

Integrator

This configuration works like a practical integrator. Most of the devices where integration operation is required, you can find this circuitry.

Op Amp Differentiator

Simulation of Non-Inverting op-amp configuration is done using Multisim 12.0.1:
