A presentation by Arsalan Qureshi student of Dawood University Of Engineering And Technology. Roll No: D-16-TE-09. This Presentation Is about op amp and its properties of integrator and differentiator.
Understand the “magic” of negative feedback and the characteristics of ideal op amps.
Understand the conditions for non-ideal op amp behavior so they can be avoided in circuit design.
Demonstrate circuit analysis techniques for ideal op amps.
Characterize inverting, non-inverting, summing and instrumentation amplifiers, voltage follower and first order filters.
Learn the factors involved in circuit design using op amps.
Find the gain characteristics of cascaded amplifiers.
Special Applications: The inverted ladder DAC and successive approximation ADC

A full stack web development course for beginners should provide a comprehensive overview of the key skills and knowledge necessary to create complete web applications, including both frontend and backend components. Here are some objectives that the course should aim to achieve:
1. **Understanding Web Technologies**:
- Learn the basic concepts of web development, including client-server architecture and the internet's functioning.
- Gain familiarity with key technologies such as HTML, CSS, JavaScript, and HTTP.
2. **Frontend Development**:
- Learn the fundamentals of HTML and CSS for building web pages and styling them.
- Gain proficiency in JavaScript for adding interactivity and dynamic behavior to web pages.
- Introduction to popular frontend libraries and frameworks such as React, Angular, or Vue.js.
3. **Backend Development**:
- Learn how to create server-side applications using languages such as Python, Node.js, Ruby, or PHP.
- Understand the role of a server in handling requests, processing data, and sending responses to the client.
4. **Database Management**:
- Understand the concepts of databases and data modeling.
- Gain experience working with relational databases such as MySQL or PostgreSQL, and NoSQL databases such as MongoDB.
- Learn how to perform CRUD (Create, Read, Update, Delete) operations on databases.
5. **API Development**:
- Learn how to create RESTful APIs for communication between frontend and backend.
- Understand how to document and consume APIs.
6. **Authentication and Security**:
- Learn methods for handling user authentication and authorization.
- Understand basic security practices such as input validation and protection against common vulnerabilities (e.g., SQL injection, XSS).
7. **Full Stack Integration**:
- Gain experience integrating frontend and backend components to create complete web applications.
- Learn how to deploy a full stack application to a hosting environment.
8. **Version Control**:
- Understand the importance of version control and learn how to use Git for collaborative development and source code management.
9. **Project Management and Best Practices**:
- Learn software development best practices such as code organization, debugging, and testing.
- Gain experience working on projects and building a portfolio of completed projects.
10. **Collaboration and Communication**:
- Develop skills in working effectively with other team members and stakeholders.
- Understand how to communicate technical concepts clearly and effectively.
By the end of the course, students should be able to create, deploy, and maintain full stack web applications with a good understanding of the technologies and practices involved.
Full stack web development encompasses the creation of both front-end and back-end elements of a web application.
Front-end development deals with designing the user interface and experience for users.
The OPerational AMPlifier or OPAMP is a versatile analog Integrated Circuit (IC) that is capable of producing a very high gain.
An amplifier is a circuit that receives a signal at its input and delivers an undistorted larger
version of the signal at its output. The operational amplifier is a high gain amplifier to which feedback is added to control its overall response characteristic.
In closed loop connection, an external resistance is connected between the output and the negative (inverting) input terminal as a negative feedback. Here, the gain can be controlled by changing the values of the resistors.
2. The Op-Amp as the no-inverting Amplifier
Aim
Feedbackcontrol of the Non-invertingOperationalAmplifierisachievedbyapplyingasmall partof
the outputsignal back to the inverting(-) inputterminalviaaRf – R2 voltage dividernetwork,again
producingnegative feedback.If the value of the feedbackresistorRf iszero,the gainof the amplifier
exactlyequal toone (unity).If resistorR2is zerothe gain will approachinfinity,butinpractice itwill
be limitedtothe operational amplifiersopen-loopdifferential gain,(Ao).

Conclusion
The secondbasic configurationof anoperational amplifiercircuitisthatof a Non-inverting
OperationAmplifier.Inthisconfiguration,the inputvoltage signal,(Vin)isapplieddirectlytothe
non-inverting(+) inputterminal whichmeansthatthe outputgainof the amplifierbecomes
“positive”invalue in contrasttothe “InvertingAmplifier”circuitwe saw inthe lasttutorial whose
outputgainis negative invalue.The resultof thisisthat the outputsignal is“in-phase”withthe
inputsignal.
