Power supply noise coupling represents a challenge in the design of current and future analog and mixed-signal circuits and systems. In this thesis, power supply noise coupling is analyzed at the circuit level. As a representative study, power supply noise coupling in a voltage reference is studied. The precision of a voltage reference circuit is critical to the performance of other analog and RF circuits. Therefore, there is much value in developing a deeper understanding of the mechanisms through which power supply noise coupling occurs in this fundamental analog and RF system building block. A model representing the amount of noise coupling in the frequency domain is developed and verified through circuit simulations. A practical design solution for increasing high frequency power supply noise rejection is identified and evaluated. Finally, the effect of technology scaling on power supply noise is studied in two successive CMOS processes.
