摘要： Disclosed herein is a Fourier transform-based phasor estimation method and apparatus capable of eliminating the influence of exponentially decaying DC offsets. According to a Fourier transform-based phasor estimation method according to an embodiment of the present invention, an input signal is sampled, and samples of one-cycle data of the input signal are separated into at least two sample groups. A Discrete Fourier Transform (DFT) is performed on each of the sample groups. A DC offset included in the input signal is calculated on a basis of results of the DFT on each of the sample groups, and an error caused by the DC offset is calculated using the calculated DC offset. A phasor of a fundamental frequency component included in the input signal is estimated by eliminating the calculated error, caused by the DC offset, from the results of the DFT on the input signal.

摘要： The present invention is related to a negative voltage generating circuit for reliably providing the semiconductor integrated circuit (IC) with a negative voltage. An electric charge pumping device generates a negative voltage by pumping an electric charge to a predetermined level supplied to one of a first node and a second node. A controlling device provides first and second pumping clock signal being clocked alternately every predetermined interval in response to a level of the negative voltage. A pumping controller controls an amount of electric charge supplied to the first node and the second node in response to the first and second pumping clock signals. Further, a reset controller resets the first node and the second node of the electric charge pumping means as the level of the negative voltage when the first and second pumping clock signals are inactivated.
