20120306476 | PHASE DETECTION APPARATUS FOR ALTERNATOR AND METHOD THEREOF - A phase detection apparatus for an alternator is disclosed according to an embodiment of the present invention. The phase detection apparatus comprises a waveform detector, a threshold voltage generator, and a comparator. The waveform detector is used for detecting a wave peak of a phase signal, and generating a waveform detection signal accordingly. The threshold voltage generator is used for generating a reference signal according to the waveform detection signal. The comparator is used for comparing the phase signal with the reference signal, and generating a comparison signal accordingly. Therefore, the phase detection apparatus for the alternator may reduce the leakage current of a battery in a vehicle. | 12-06-2012 |
20120038408 | INTEGRATOR CIRCUIT - An integrator circuit is provided in the present invention, which utilizes a first capacitor and a first switching unit to sample an input signal and carries out distribution of charges between the first capacitor and a second capacitor. The second capacitor is larger than the first capacitor in capacitance. The integrator circuit transmits the charges stored in the second capacitor to a node of the first capacitor which is coupled to a ground previously. Accordingly, a direct current voltage level of the first capacitor may increase, facilitating an increase in a direct current voltage level at the second capacitor. Thereby, the accuracy and linearity of the integrator circuit may improve. | 02-16-2012 |
