Hi all,
Which noise is larger in SoCs, battery noise or switching regulator output ripple?
The switching regulator output ripple is about several tens of mV at the switching frequency. How about noise at the output of the battery, what is its amplitude and the frequency content? How the bulk capacitor near the battery and decoupling capacitors near the input of each submodule suppress the battery noise?
The output noise of battery may be very application-dependent. In what case (application) the battery noise would be smaller than the switching regulator output ripple, and in what case the battery noise would be larger?
Thanks in advance.
