Hybrid Digital Linear And Switched Capacitor Voltage Regulator
Abstract: An on-die voltage regulator (VR) is provided that can deliver much higher conversion efficiency than the traditional solution (e.g., FIVR, LDO) during the standby mode of a system-on-chip (SOC), and it can save the power consumption significantly, during the connected standby mode. The VR operates as a switched capacitor VR under the low load current condition that is common during the standby mode of the SOC, while it automatically switches to the digital linear VR operation to handle a sudden high load current condition at the exit from the standby condition. A digital proportional-integral-derivative (PID) controller or a digital proportional-derivative-averaging (PDA) controller is used to achieve a very low power operation with stability and robustness. As such, the hybrid VR achieves much higher conversion efficiency than the linear voltage regulator (LVR) for low load current condition (e.g., lower than 500 mA).
