Abstract
With perpetual electrification and highly dynamic
operations, modern automotive ICs face unprecedented elec-
tromagnetic interference (EMI) challenges. To address such,
this article presents a condition-adaptive 1 f 3 EMI control for
automotive power circuits, which coordinates integral spread-
spectrum modulation (SSM) schemes to regulate EMI adaptively
in response to drastic condition changes of input voltage VIN
and load current ILOAD. Specifically, a 1 fSW,UP/DN spread control
technique stee
