Abstract: With the rapid growing demands on data transmission and processing in a world of big data and artificial intelligence, the power consumption of the information industry sees an exponential increase. Then, the energy efficiency of the microprocessors becomes more important from both thermal and energy perspectives. Per-core dynamic voltage and frequency scaling (DVFS) technology is proven to be an effective way to improve the digital system energy efficiency. But, per-core DVFS requires high current density fast-transient integrated voltage regulators (IVRs) at the point-of-load (PoL) to enable and support it. Recently, the advanced 3D packaging technologies enabled more design flexibility and topology innovations for the PoL IVRs. This talk will introduce our recent advances on PoL IVRs, including switching power converters as well as linear low-dropout regulators.
