Capacitor-less low dropout regulator using dual feedback loop structure

A capacitor-less low dropout regulator using a dual feedback loop structure, comprising:

• a capacitor-less dual feedback loop unit including a plurality of feedback resistors, an error amplifier, and a transconductance cell (hereinafter, referred to as a gm cell) to form a main loop passing through the error amplifier and a sub-loop passing through the gm cell without passing through the error amplifier;
• a dynamic compensation unit connected to a first main pole located at an output of the error amplifier and a second main pole located at an output of the gm cell to provide dynamic frequency compensation using a Miller effect to the first main pole and the second main pole according to a load current of the capacitor-less dual feedback loop unit;
• and
• a load current measurement unit configured to measure a load current of a third main pole formed at a load of the dual feedback loop unit to provide the load current to the dynamic compensation unit.
