    • The present invention provides a device and process for capacitive linear displacement measurement, wherein the strip electrodes are arranged on the base in a line equidistantly, and every N continuous strip electrodes compose a spatial period, and a first group of signal lines is composed by N signal lines, wherein N is an integer greater than or equal to 2; in the absolute displacement measurement mode, the N signal lines in said first group of signal lines take turns in being loaded with excitation signals in one signal generation period; the connection between each strip electrode and the first group of signal lines causes all the excitation signal combinations detected at all displacement positions by the reading unit in the absolute displacement measurement mode to be different from one another; the reading unit moves along the strip electrodes, outputting the signal combinations detected at the strip electrodes which it covers, and providing the absolute displacement value corresponding to the signal combination to the displacement determining unit. The present invention enables simpler absolute displacement measurement at a low cost and delivers strong resistance to interference.

    • A voltage regulator is provided having one or more discharger circuits that compensate for low on-chip output capacitance and a slow loop response time. In one embodiment, the voltage regulator includes an output transistor coupled to an output voltage line, an output voltage sensing arrangement coupled to the output voltage line for producing an output feedback voltage, and an error amplifier coupled to the output feedback voltage, the output transistor, and a reference voltage for applying feedback control to the output transistor. A first discharger circuit is coupled to the output voltage line and to a reference potential, the first discharger circuit being triggered by a steep-rise overvoltage condition. In another embodiment, a combination of fast and slow discharger circuits is used to improve the load step response - i.e., to stop the output voltage from jumping too high and to pull it back to stable value very quickly, such that the load circuits are protected.
