Feedback Type Voltage Regulator

摘要

The present invention discloses a feedback type voltage regulator, including a voltage reference circuit for providing a reference voltage, distributed series feedback amplifiers electrically coupled to the voltage reference circuit and a power transistor which gate is electrically connected to the distributed series feedback amplifiers. The distributed series feedback amplifiers comprises three set of amplifiers serially connected with each other, wherein the relation of the gain of the first amplifier (A1), the second amplifier (A2), and the third amplifier (A3) is A1>A2>A3, wherein the relation of the bandwidth of the first amplifier (B1), the second amplifier (B2), and the third amplifier (B3) is B1
