| الوصف: | This work presents a fast-transient and synthesizable clock-domain-crossing (CDC) controller for the design of fully integrated digital low-dropout regulators (DLDOs). The proposed CDC controller consists of two sub-controllers and achieves both fast response and fast settling for consecutive loading/unloading activities of digital loads. Once a load transient event is captured by the undershoot detector, it triggers the event-driven sub-controller (EDC) and the MSB unary-weighted power gates (PGs) are successively activated until the output voltage is pulled up to the normal range. Then the synchronous computational sub-controller (SCC) takes over the regulation task and continuously computes the optimal code for PGs according to the digitized sample of the output voltage. Unlike conventional dual-loop designs, the two sub-controllers share the same PGs for area saving. The proposed technique is implemented with a 65-nm CMOS process, and it achieves a 1.7-ns response time and a 180-ns settling time for a 6.75-mA load current step with a 100-ps edge time. The 0.254-ps FoM is the best one among prior-art fast-transient controller designs. |
