A new chaotic oscillator which can be implemented on standard CMOS process is presented. The circuit generates double-scroll chaotic attractor and is suitable for high-frequency operation. As a possible application, the use of the circuit as the core of a random number generator (RNG) is illustrated. The quality of the RNG is investigated using standard statistical tests (according to FIPS-140-1 and NIST 800-22) and it is shown that the generated binary sequences have good statistical properties.
