Chaotic synchronization using monolithic Chua oscillators

This paper presents experimental evidence of the synchronization between two monolithic chaotic oscillators. These oscillators have been fabricated using g(m)-C design techniques in a 2.4 mu m double-poly n-well CMOS technology. The circuit realizes an oscillator from Chua's circuit family and features electrical control of the parameters in the piecewise-linear function and on-chip tuning of the oscillator natural frequencies. The area of the circuit including pads is 5 mm(2) and the power dissipation is less than 1.8 mW for a symmetrical biasing of +/- 2.5 V.
