  • Linear regulator with real-time frequency compensation function
    Patent number: 10101758
    Abstract: The present invention relates to a linear regulator with real-time frequency compensation function, which belongs to the technical field of analog integrated circuits. The part of frequency compensation of the present invention includes the dual-frequency compensation networks and compensation transfer switcher, and the pulse delay circuit. The dual-frequency compensation networks and compensation transfer switcher provide the corresponding frequency compensation for linear regulator under two different capacitive loads. The pulse delay circuit generates a set of signals which have a delay related to the switch-pulse signals to control the access of the compensation transfer switcher and capacitive load.
