Abstract

The paper presents a switched-current circuit implementation of a chaotic algorithm to generate a white noise. A 3-bit digital normalizer is utilized to adjust the coefficients in the piecewise-linear transfer function such that the probability of the generated numbers will be very close to a uniform distribution. A 1.0-GHz linear track-and-hold circuit is applied in the random number generator (RNG) to achieve a wide output bandwidth. TSMC 0.25-μm one-poly five-metal CMOS process is adopted to carry out the proposed design to verify the wideband performance. When the operating clock is 10.0 MHz, the measured bandwidth of the generated noise is 4.0 MHz.
