ON-CHIP LOW VOLTAGE CAPACITOR-LESS LOW DROPOUT REGULATOR WITH Q-CONTROL |
摘要 |
Systems and method for a capacitor-less Low Dropout (LDO) voltage regulator. An error amplifier is configured to amplify a differential between a reference voltage and a regulated LDO voltage. Without including an external capacitor in the LDO voltage regulator, a Miller amplifier is coupled to an output of the error amplifier, wherein the Miller amplifier is configured to amplify a Miller capacitance formed at an input node of the Miller amplifier. A capacitor coupled to the output of the error amplifier creates a positive feedback loop for decreasing a quality factor (Q), such that system stability is improved. |
