 23 Feb 2007 1:15 A random generator schematic |
|

Hi dudes!
I've searched the forum and googled for a while, but nothing really useful came in place. I'm looking for a few ideas that generate random noise/data, and in case of noise, a schematic to convert them to bits.
Has anyone made something like this before?

| Is it possible to implement the circuit in IC? Any articles about practicle implementation of RNG in IC? TIA.

thanks IanP!
I was wondering: is it possible to use flip-flops, for example, or nor/nand gates, putting them in a race condition? The differences between transistors will definitely have a word here, but are them good enough to provide a reliable entropy?
Another idea i was thinking of is getting an uninitialised memory location in a PIC, sending it, and then triggering a powerdown/powerup of the device.
What do you think?

| Yes, I have. I did it entirely in software on a PIC. It was random enough for me. What's your application?

Can you put on your application.

If you mean that u wanna design it as ASIC, it's absoulutely yes! it can be..
it can even been synthesized from normal FPGA flow..
