Operational Amplifier Based Function Generator
Introduction:
In these papers I will talk about op-amp to make function generator, and generate square, triangle and sine waves. Op-amp (operational amplifier) is a fundamental active element of analog circuit design. The first op amps were vacuum-tube circuits consuming lots of space and energy but Modern op amps are fabricated as integrated circuits that bare little resemblance to the early circuits. Today, op amps are monolithic integrated circuits, highly efficient and cost effective. The term operational amplifier evolved from original applications in analog computation where these circuits were used to perform various mathematical operations such as summation and integration. The fig (1) is about op-amp : V+: non-inverting input
V−: inverting input
V out: output
VS+: positive power supply
VS−: negative power supply

And we can simplify this and how will this work by just get the brief about what inside the triangular!
