Abstract
An internal power generation circuit comprises: a first internal power generation circuit, configured to generate a first power signal based on an external power signal, and including an NMOS transistor, voltage of the first power signal being lower than voltage of the external power signal by threshold voltage of one NMOS transistor, wherein the circuit further includes: a booster unit performing boosting on the first power signal, voltage of a boosted signal being higher than the voltage of the first power signal by at least the threshold voltage of one NMOS transistor; a self-starting feedback circuit configured to generate an output voltage signal based on the boosted signal and the external power signal, wherein before the output voltage signal reaches a target voltage, the output voltage signal follows the external power signal, and after the output voltage signal reaches the target voltage, the output voltage signal holds the target voltage.
