Switched-Mode-Control Based Hybrid LDO for Fine-Grain Power Management of Digital Load Circuits.

Switched-mode-control (SMC) is a control methodology that allows instantaneous switching between controllers to extend the dynamic range of feedback circuits. A hybrid low dropout voltage regulator utilizing SMC is designed in 130 nm CMOS for fine-grain power management, fast droop recovery, and accurate voltage regulation of digital load circuits. The design provides an optimal tradeoff between p...
