1 Defining noise and precision in a power architecture
Noise is often application-specific, but in the context of this paper, noise is any unwanted signal that originates from thermal noise, 1/f noise and low-frequency oscillations, up to approximately 100 kHz.
2 Innovations in low-noise and low-power voltage references
Reducing noise in power architectures helps increase an analog-to-digital converter's resolution and precision but creates design challenges with power consumption, printed circuit board (PCB) size, manufacturing flow and cost.
3 Innovations in precision battery monitoring
Having creative solutions in silicon technologies enables designers to optimize their power architectures and battery systems.
