Ground Shifting in Capacitive Sensing Applications
Texas InstrumentsProximity sensing is a key feature in many smart applications. This feature is used for system wake-up, collision avoidance, and gesture recognition. Capacitive sensing solutions are typically implemented to achieve simple yet robust proximity detection. This application note reviews important system considerations when designing with Texas Instruments' resonator-based capacitive sensing chips, the FDC2x1y family. Guidelines for sensor system design and grounding techniques are provided through mathematical modeling and qualitative assessment of external parasitic capacitance.
Accuracy-Enhanced Ramp-Generation Design for D-CAP3 Modulation (Rev. A)
Texas InstrumentsD-CAP and D-CAP2 control schemes have been widely used in TI Switched-Mode DC-DC converters due to their fast transient response and no off-chip compensation. Offset generated by current sense ramp adds an error to VFB and Vout and hence reduces DC accuracy. This paper introduces a new D-CAP3 control scheme which greatly improves DC accuracy of the converter while maintaining the same fast transie
