Abstract:
On embodiment of a device with a noise adaptive power supply includes a noise adaptation unit configured to receive a noise adaptation signal. The noise adaptation unit can provide processing, such as digital filter processing to reduce the effect of power supply noise. In one embodiment, a feedback signal is used to adjust the output voltage of the power supply. The noise adaptation signal can be similar to the feedback signal. The noise adaptation unit can provide the processing in response to the noise adaptation signal.
