Abstract
The present invention provides a power regulation system and method with high speed signal settling capabilities for providing rapid active transient response to a microelectronic device. An active transient response system includes a power supply configured to receive external and/or internal signals indicating the occurrence of transient load conditions and to respond to the transient load conditions based on one or more of these signals. The system may further include a transient suppressor configured for early detection of transients, assisting in transient suppression, and early signaling of transient activity to the power supply.The system provides rapid recovery to steady state operation from the active transient response mode by using a digital compensator to quickly modifying the duty cycle and provide a voltage offset proportional to the transient microprocessor load step. Recovery is further improved by current rephasing techniques.
