Zusammenfassung: | In certain embodiments, a method includes performing a first positive integration by sensing a first rising edge of a charging signal of a touch sensor during a first synchronization period, performing a first negative integration by sensing a first falling edge of the charging signal during a second synchronization period, and performing a first phase shift by skipping integration during a third synchronization period. The method further includes performing a second positive integration by sensing a second rising edge of the charging signal during a fourth synchronization period, performing a second negative integration by sensing a second falling edge of the charging signal during a fifth synchronization period, and performing a second phase shift by skipping integration during a sixth synchronization period. The first integrations are associated with a first sample measurement and the second integrations are associated with a second sample measurement. |
