Abstract: The adjustment of stimulation signal amplitudes in capacitive touch sensor panels and/or styli to reduce power consumption while preserving satisfactory touch performance is disclosed, in particular in situations where the noise level is not significant and there is excess SNR margin. To accomplish this, one or more metrics can be measured, calculated or otherwise determined to use as a predictor of touch performance, and these metrics can be processed to determine the minimum stimulation voltage required to maintain acceptable touch performance.
