Analog Op-Amp Circuits

he very first designs that came about were analog designs, a Vacuum Tube amplifier is an example. Analog is the representation of data or physical parameter in an accurate and precise decimal number like +72.182 mV. The greater the resolution required, the more demanding is the design for achieving high accuracy and low drift.

As an analogy, see the conventional water tap as an analog control, an electric light ON-OFF switch as a digital control. After the handheld Abacus calculator (low-power, durable, bio-degradable), Mechanical and electro-mechanical computers were made and studied, The very first electronic computers were Analog Computers using an opamp as a building block.

Operational Amplifiers

With a few Op-Amps and a regulated Power supply, many Instrumentation and Process control equipment can be designed. The Human Brain understands Numbers, Quantity and it regulation very well ! On the right you can see a analog controller based on opamps and discrete devices. A Heater, Fan and Motor is regulated, controlled and timed for a process.


Analog Controller based on Opamps
Analog is about numbers, the circuits can be understood and designed mathematically or empirically. Designing and Building a True RMS Rectifier with Op-Amps, will help a designer digest many Op-Amp capabilities.

Product Development Fundamentals

Electronic Product Design and development capability can be refined and enhanced only by practical experience. A student can learn these aspects by working in a Engineering Service Company.

Building Custom design Solutions for clients will build skills of component selection, black box specs, customer communication and prototype testing among many others.

A. Product Design Sections :
  1. Electronic Engineering - Circuit Design, PCB Design, EDA. 
  2. Mechanical Engineering - CAD, Tool and Die Design, Enclosure 
  3. Software Engineering Firmware - PC ware, CASE, emulators 
B. Methods of Product Design :
  1. Design Automation. - Design and Simulation with Computer. 
  2. Computer Aided Design - Design on Computer, Breadboard test. 
  3. Conventional Design. - Paper design with Breadboard test

Amps-n-Volts eMag

Near 2001 i started sharing my learning and experience in Electronics Engineering on Blogs and Newsletters. One of the Successful eMag and electronic email magazine ran for five years. I lost interest later in the email mag, and this magazine just morphed into a dozen or more Tech Blogs that run today.

From the feedback i got, it has helped engineers and enthusiasts worldwide in Electronic Product Design.

Amps-n-Volts Notes Corrected Improved

These blogs contain most of the Magazine - Schematics of delabs - Soldermans Basics - Circuits Faq

My knowledge is limited to my experience, observation, perception, learning and beliefs, but i have to express my views freely. These posts are mirrored in design devices.
