Sensitivity

To show sensitivity, in terms of farads, the internal reference capacitor is used as the change in capacitance. In the mutual-capacitance case, the 0.1-pF capacitor is used. In the self-capacitance case, the 1-pF reference capacitor is used. For simplicity, the results for only button 1 on both the CAPTIVATE-PHONE and CAPTIVATE-BSWP panels are reported in Table 7-1.

Table 7-1 Button Sensitivity

CONVERSION COUNT CONVERSION GAIN CAPTIVATE-PHONE BUTTON 1 CAPTIVATE-BSWP BUTTON 1
CONVERSION TIME (µs) COUNTS FOR 0.1-pF CHANGE CONVERSION TIME (µs) COUNTS FOR 1-pF CHANGE
100 100 25 6 50 8
200 200 50 10 100 16
200 100 50 21 100 31
800 400 200 70 400 112
800 200 200 140 400 202
800 100 200 257 400 333

An alternative measure in sensitivity is the ability to resolve capacitance change over a wide range of base capacitance. Table 7-2 shows example conversion times (for a self-mode measurement of discrete capacitors) that can be used to achieve the desired resolution for a given parasitic load capacitance.

These measurements were taken with the CapTIvate MCU processor board with the 470-Ω series resistors replaced with 0-Ω resistors.
0-V discharge voltage is used.
