Abstract :
A three-transistor CMOS circuit is presented, with adjustable nonlinear characteristics, which can be used as a map that generates discrete-time chaotic signals. A method of constructing a chaos generator using two map circuits is also proposed. The circuit is very compact, which makes it suitable for applications requiring the integration of a large number of random signal generators on a single VLSI chip.
