Abstract
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 and performing a first negative integration by sensing a first falling edge of the charging signal during a second synchronization period. The method also includes toggling the charging signal, resulting in a second rising edge of the charging signal during the second synchronization period. The method further includes performing a second negative integration by sensing a second falling edge of the charging signal during a third synchronization period and performing a second positive integration by sensing a third rising edge of the charging signal during a fourth synchronization period. The first integrations are associated with a first sample measurement and the second integrations are associated with a second sample measurement.
