Abstract: Various aspects of the present disclosure generally relate to control of a user device under a wet condition. In some aspects, a user device may determine whether the user device is operating under a wet condition; select, based at least in part on whether the user device is operating under the wet condition, a set of input components to control the user device, wherein the set of input components is selected from a plurality of different sets of input components; and configure a user interface of the user device according to the set of input components. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure are generally directed to circuitry and techniques for current sensing. For example, certain aspects provide a circuit for signal amplification including a first amplifier, a second amplifier, and a third amplifier. The circuit also includes a first capacitive element coupled between a first output of the first amplifier and a first input of the third amplifier, a second capacitive element coupled between a second output of the first amplifier and a second input of the third amplifier, a third capacitive element coupled between a first output of the second amplifier and the first input of the third amplifier, and a fourth capacitive element coupled between a second output of the second amplifier and the second input of the third amplifier.
