It’s a field that need not be expensive or difficult to work in, as [Henk Mulder] shows us with his 4-bit analogue random number generator ... bits he’s using four identical circuits, with ...

Random generator: The digital circuits at the center of this electron micrograph image can emit a stream of random numbers at high ... proving it can be built using 32 and 22 nanometer ...

Even RFID tags could get ‘true’ random number generators following work at the Queen ... For FPGAs there are three circuits based on: a single XOR gate, a single LUT (look-up table), or a multiplexer ...

It’s quantum, it’s chaotic, it makes for a great source for a random number generator, and there are already dozens of prototype circuits around the Internet. [Ian] took one of these circuit ...
