Abstract :
In this work a discrete-time CMOS analog/digital white-noise generator is presented. The proposed circuit implements a discrete-time deterministic-chaos algorithm that can theoretically issue both delta-correlated analog-value sequences and delta-correlated 1-bit digitized sequences. SPICE simulations state a white-sequence generation maximum frequency above 10 MHz
