Abstract :
A chip has been designed to test the implementation of a PLL-based dynamic supply controller. Separating the rate transitions from V/sub T/ and temperature drift improves loop transient response. Buffering and explicit averaging can be used to smooth workload. Active damping minimizes loss in the supply filter due to voltage transitions.
