The following is the summary of my work in the week of Feb 06 - Feb 13. 1. Implemented and did simulations on the multiple phase PFM design. Under two phases the power efficiency could be over 80% and the ripple is less than 5%. 2. Finished proofread of the floorplanning Journal paper and submitted to TVLSI. 3. Finished the SRC slides for co-optimization on micro-architecture configurations and floorplanning.
