DESIGN STRATEGIES AND DECOUPLING TECHNIQUES FOR REDUCING THE EFFECTS OF ELECTRICAL INTERFERENCE IN MIXED-MODE ICS

A key issue in the successful integration of analog circuits is a stab le analog power supply. Traditional on-chip decoupling methods exhibit transients in the supply of voltage drops and power losses. This pape r introduces the RLC decoupling method that features an enhanced trans ient response while being especially suited for low-power, low voltage applications. Both a theoretical and a practical approach are present ed together with measurement results. As the benefits of a stable loca l power supply can be lost by the inadequate connection of two subcirc uits with relative variations on the local grounds, a differential app roach of signal transfer is proposed. Furthermore, the effect of a goo d local decoupling can be deteriorated by substrate noise, so some att ention is given to this problem too.
