Measure Capacitive Sensors With A Sigma-Delta Modulator
Capacitive sensors supply high accuracy at a relatively low cost. But system designers attempting to use them have been forced to first convert the capacitance to a voltage, then convert the voltage into the digital domain using a precision analog-to-digital converter (ADC). The complex circuit design, lengthy prototype evaluation, and demanding system test usually cause the designer to look for a different sensor. They often select one that's more expensive, less accurate, or...
