An Autonomous Reconfigurable Power Delivery Network (RPDN) for Many-Core SoCs Featuring Dynamic Current Steering

Abstract

A 2-input/4-output autonomous RPDN in 14nm CMOS with dynamic current steering enables better core-count and FIVR scalability for many-core SoCs in scaled process nodes while improving the overall area efficiency of on-die power delivery/management circuits by 35%. The RPDN controller minimizes losses for a variety of operating conditions to improve overall energy efficiency in most runtime scenarios while complying with all local and global current limits.
