Abstract :
A feedback circuit consisting of a three-stage array of weighted CMOS inverters, two CMOS transmission gates and a holding capacitance generates chaos. Trajectories can be designed from the transfer characteristics of the three-stage array of weighted CMOS inverters, which directly produces a nonlinear mapping function. The chaotic trajectories were observed via a bitmap display
