Abstract
An electronic device can be configured to operate in a plurality of operating modes to generate various stimulation signals for touch sensing operations. Switching circuitry can selectively couple one or more stimulation circuits to touch stimulation circuitry to reduce electromagnetic interference generated during transitions between the plurality of operating modes. The electronic device can transition from a stimulation phase to a termination phase at an arbitrary time, unconstrained by integration time requirements of accompany touch sensing circuitry.
