Here this circuit is based on the principle of audio amplification using operational amplifier and pulse width modulation using 555 Timer. In this article we are describing the principle, design and ...

Are your jellybeans getting stale? [lcamtuf] thinks so, and his guide to choosing op-amps makes a good case for rethinking what parts you should keep in stock. For readers of a certain vintage, the ...

Op amps are the basic building blocks for much of linear circuit design. You probably learned about them in college and even designed some products containing an op amp. As an electronic engineer, you ...

The operational amplifier, or op amp, is one of the most basic building blocks used in analog circuits. Ever since single-chip op amps were introduced in the 1960s, thousands of different types have ...

Many single-supply operational amplifiers are capable of rail-to-rail input operation, if they have the proper input circuitry to support this function. This article is an expansion of the blog post ...

This course builds on the fundamentals of DC and AC electrical circuit analysis. It provides an introduction to the design and building of analogue electronic systems. The course will cover a blend of ...

The power transistor must be chosen to provide fast response while also withstanding high power dissipation. Several electrical and thermal characteristics must be considered: 1. An array of N current ...
