Abstract
Input members with capacitive sensors are disclosed. In one embodiment of an electronic button, a first circuit is configured to capture a fingerprint of a user's finger placed on the electronic button, and a second circuit is configured to sense a force applied to the electronic button by the user's finger. The first circuit is further configured to provide temperature information to compensate for temperature sensitivities of the second circuit, and the second circuit is further configured to provide force information to the first circuit.
