A new cross-coupled LC chaos oscillator suitable for IC realisation is presented. The proposed circuit was fabricated using a 0.35 µm CMOS process and test results showing its feasibility are given. As a possible application, a method for using the proposed oscillator as the core of a random number generator is described. Experimental binary data obtained according to the proposed method pass the four tests of FIPS-140-2, the full NIST-800-22 and DIEHARD random number test suites.
