Digital Control of Switching and Linear Integrated Voltage Regulators

Abstract

This work presents a summary of the digital control techniques in todays advanced, state of the art IVRs and the role digital control is playing to enhance their key performance metrics. Examples from high switching frequency Buck converters, computationally controlled digital LDOs as well as digitally assisted analog and hybrid LDOs speaks not only to the growing popularity of digital control in a wide variety of applications but also demonstrates its suitability on advanced process nodes which is inherently tough on analog circuits.
