A low voltage low power fully integrated chaos generator is presented in this paper. Comparing with the conventional off-the-shelf electronic components-based chaos generators, the designed circuit is fully integrated, and it achieves lower supply voltage, lower power dissipation and smaller chip area. The proposed fully integrated chaos generator is verified with GlobalFoundries 0.18 mu m CMOS 1P6M RF process using Cadence IC Design Tools. The simulation results demonstrate that the fully integrated chaos generator consumes only 17 mW from +/- 2.5 V supply voltage. Moreover, the chip area of the chaos generator is only 1.755 mm(2) including the testing pads, and it has a wide range of practical application prospects.
