Performance-oriented scaling laws for mixed analog/digital MOS circuits

A novel approach, in which S/ N performance is taken as the key figure, is presented for scaling of mixed analog/digital circuits. S/ N performance is severely degraded by other popular scaling laws. The proposed laws, (i) hold the low-frequency S/ N ratio a constant (ii) are, in general, compatible...

Description
Summary:A novel approach, in which S/ N performance is taken as the key figure, is presented for scaling of mixed analog/digital circuits. S/ N performance is severely degraded by other popular scaling laws. The proposed laws, (i) hold the low-frequency S/ N ratio a constant (ii) are, in general, compatible with the present popular trends in scaling, and can also (iii) improve the required d.c. or a.c. response of the scaled circuits. Improved MOS analog circuit performance is verified by SPICE simulations.
