Abstract :
A chaotic transmitter and a synchronized chaotic receiver have been designed in a 0.25 μm CMOS process. Both transmitter and receiver use conversions between voltage and time to implement nonlinear tent-map functions. The transmitter outputs chaotic pulse position modulated (C-PPM) data as a stream of 2.3 V p-p pulses of <1 ns duration. The chaotic receiver uses the timing information between pulses to regain the chaotic state of the transmitter. The receiver resynchronizes within five cycles in a noise-free environment if lock is lost from the transmitter. The maximum throughput is 20 Mb/s and the bit error rate (BER) is <10-9. The transceiver is realized on a 2.5 mm×1.5 mm die and dissipates 375 mW
