## The theory behind oscillator circuit

Hi,

I am learning about oscillator circuit, in my text book draw out a basic configuration of oscillator circuit and from it they introduce the configuration of colpitts and Hartley oscillator and so on.I want to understand deeply about it but I can find where to give me detail about it.Would you help me explain why the oscillator have to configuation like that? Or can you show me where i can find the answers.

Please see my attachment.

Thanks in advance.

just use google like i didTo all posters

1)please provide all info...remember half baked cake tastes like shi... so don't post half circuits people here really like to help but they need full info.

Thanks in advance

## Re: The theory behind oscillator circuit

I've come to realize that several people tried arranging components in many different ways, and did lots of adjustments, in the early days while attempting to make an oscillator around an LC loop.

I presume Mr. Colpitts was the first one to succeed (or perhaps the first one to publish).

He may or may not have known what mathematical formula to use. I suspect the math came later.

To aid in visualizing its concept of operation, I have put videos on Youtube showing animated simulations of different oscillators (transistor versions). These show the dynamics of coil action, capacitor action, and current bundles flowing through wires.
