A Fully Integrated Buck Voltage Regulator in 16nm with in-Package Air Core Inductor Featuring Digital Computational Control for Fast Transient Responses
This paper presents a fully integrated buck voltage regulator in 16 nm CMOS with in-package air-core inductors. A digital computational non-linear controller is proposed demonstrating 20 ns response time with 25 mV droop at <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$1 \mathrm{A} / 0.4 \text{ns}$</tex> load step.
