摘要： A linear voltage regulator, such as a low-dropout regulator, supplies power to one or more digital circuits within a computer system. The low-dropout regulator provides a substantially constant output voltage independent of loading conditions. The low-dropout regulator is biased at a relatively low operating current for steady-state operation to improve power efficiency of the low-dropout regulator. During a loading condition change, an adaptive biasing circuit senses the loading condition change and provides additional biasing current to momentarily increase the operating current of the low-dropout regulator to improve transient response.

摘要： A variable reference voltage generation unit used in DC/DC converter includes a sample-hold valley inductor current unit electrically connected to a reference voltage generation unit. The sample-hold valley inductor current unit receives the valley inductor current and converts it into the valley voltage. The reference voltage generation unit receives and converts a current signal two times of a designated current into a voltage signal two times of a designated voltage. The voltage signal two times of reference voltage is then subtracted by the valley voltage to produce the new reference voltage to compare with an inductor voltage for controlling the switching of a switching transistor of the DC/DC convertor.
