DIGITALLY CONTROLLED SENSOR SYSTEM

摘要

Systems and methods for digitally controlling sensors, one embodiment being a digital controller for a capacitance diaphragm gauge which is embedded in a digital signal processor (DSP). The digital controller receives digitized input from a sensor AFE (30) via a variable gain module, a zero offset module and an analog-to-digital converter. The controller automatically calibrates the received input by adjusting the variable gain and zero offset modules.
