发明名称 Q値を調節することのできるオンチップ低電圧キャパシタレス低ドロップアウト調整器
摘要 <p>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.</p>
