Dynamic compensation ldo
WebAn active-frequency compensation circuit is introduced in [5] to greatly ... As shown in Fig. 1, the basic structure of this ultra-fast capacitor-less LDO is similar with [13] focusing on dynamic biasing. It is constructed by two differential common-gate transconductance cells, a voltage buffer, a current-summation circuit and an ... WebSo, a load-tracking technique [1] is used in this LDO by sensing the load current. In CB2, both Ms1 and Ms2 can be used to sense the current of Mp (the power transistor of LDO). Also, Ms1 can be used to reduce the impedance at node 1 to 1/gm _Ms1 and the pole at this node is pushed to further frequency than the dominant pole at output of LDO.
