Methods and devices to mitigate time varying impairments in sensors are described. The application of such methods and devices to pressure sensors facing time varying parasitic capacitances due to water droplets is detailed. Benefits of auto-zeroing technique as adopted in disclosed devices is also described.

Parasitic insensitive sampling in sensors

Novel integrated circuit environmental and temperature sensors in combination with measurement circuitry fully integrated as part of an ASIC die, which may be co-packaged with a pressure sensor integrated circuit to create a compact yet sensitive environment monitoring product. Embodiments may include one or more integrated local heating elements and control circuitry that are power supply independent, make efficient use of battery power, include an accurate in-built temperature detection capability, and provide digital close-loop control of the heating elements.
