PPPEAC hosted a technical seminar on Monday, December 7, 2020, from 4:30 to 5:30 PM. The seminar ran on Zoom, hosted by Princeton University. Dr. Kaladhar Radhakrishnan of Intel was the speaker.
Power Delivery Challenges and Solutions for High Performance Microprocessors
Power delivery grew more complex as microprocessor power levels and core counts rose, especially after Dennard scaling broke down in the mid-2000s. Integrated voltage regulators (IVRs) are a key response. They range from simple power gates to fully integrated switching regulators. The talk covers how engineers judge IVRs on conversion efficiency, current density, load regulation, and configurability. It also covers the performance targets and the solution approaches the industry is pursuing.
