regenrative

regenrative receiver? does any one know how it works? does any one have a useful document on it. including a circuit with it explanation
Thanks:D

Google will find lots of info, but you must spell it correctly. ;)
Search for "regenerative receiver" or "regenerative radio".
Good dictionary info:

Here's one of many construction projects, including circuit description:

It is basically a device, like a bipolar transistor, set up to oscillate. But there is a RC bias circuit (with an audio frequency time constant) that quenches the oscillations just at the point that it is ready to take off. Since an oscillator has "ionfinite gain", this almost oscillator has almost infinite gain. Not a bad trick for one device.
