Power supply noise (PSN) coupling represents a challenge in the design of current and future analog and mixed-signal circuits. This paper studies the impact of PSN coupling on a key analog circuit building block: a voltage reference. A model representing the amount of noise coupling in the frequency domain is developed and verified through simulations. A design solution for increasing high frequency PSN rejection is identified and evaluated. Finally, the effect of technology scaling on PSN is studied in two successive CMOS processes.
