DESCRIPTION:Barometric pressure sensors are indispensable features in weara
 ble consumer devices. Modern designs can sense absolute height difference 
 of less than 8.5cm (1Pa)\, improving indoor navigation significantly and e
 nabling new applications such as activity tracking and crash detection. In
  this talk\, we will take a deep dive into the design challenges of readou
 t chains for capacitive pressure sensors. The main driving requirements ar
 e noise and power. To reach the demanding targets for wearable devices\, h
 eavy duty cycling and advanced analog front-end design is needed. But thes
 e are not the only challenges. Since they must be exposed to the atmospher
 e\, pressure sensors in smartphones are often located in their outer cases
 \, and have long connections to the main PCB. This leads to high demands o
 n their PSRR and RF immunity. Both topics will be discussed\, as well as s
 everal methods to improve the robustness of pressure sensor readout chains
