Abstract
In one embodiment, a device comprises one or more memory units collectively storing logic configured to cause one or more processors to perform operations. The operations comprise: obtaining a first measurement associated with a first voltage output by a mutual-capacitance measurement circuit; obtaining a second measurement associated with a second voltage, the second voltage output by the mutual-capacitance measurement circuit in response to a first change in capacitance; obtaining a third measurement associated with a third voltage output by the mutual capacitance measurement circuit, the third voltage being different from the first voltage; and obtaining a fourth measurement associated with a fourth voltage, the fourth voltage output by the mutual-capacitance measurement circuit in response to a second change in capacitance. The operations further comprise calculating a differential measurement using a difference between the first measurement and the second measurement and a difference between the third measurement and the fourth measurement.
