Low-voltage low-power CMOS analogue circuits for Gaussian and uniform noise generation

A CMOS analogue circuit for Gaussian noise generution as well as a novel circuitfor transforming Gaussian noise into uniform noise, hoth.designed/or operating with a supply voltoge o/ I . S K arepresented. Both circuits are optimizedfor U 0 . 3 5 ~ standord CMOS technology using an equation-based design methodology based on generic algorithms. Electrical simulations demonstrate that high noise amplinrdes together with reasonable hondwidths can be achieved with relatively low power dissipation. Potential applications include self-calihrution and on-chip self-testing of video-rate analogue-to-digital converters.
