摘要： A voltage-averaged temperature compensation method at start-up. The method implements two pluralities of PMOS devices such that a respective voltage-averaged temperature compensation circuit produces a first temperature voltage and a second temperature voltage to compensate temperature effect and accordingly produces an output voltage having a damping waveform in lower region when activating the first plurality of PMOS devices and a desired waveform in upper region when activating the second plurality of PMOS devices. As such, the error reference or control due to a prior damping waveform is eliminated.
