    Abstract: The present invention discloses an LDO (Low DropOut) linear voltage regulator, which is based on an NMC (Nested Miller Compensation) architecture and can be capacitor-free, wherein an active resistor is added to the feedback path of the Miller compensation capacitor to increase the controllability of the damping factor, solve the problem of extensively using the output capacitor with a parasitic resistance, and solve the problem that a compromise must be made between the damping factor control and the system loop gain. Further, the present invention utilizes a capacitor-sharing technique to reduce the Miller capacitance required by the entire system and accelerate the stabilization of output voltage without influencing stability.

    Abstract: A liquid crystal display (LCD) driver has the characteristic that using a voltage-switching control circuit to receive the liquid crystal positive voltage and the segment positive voltage generated by the driving voltage generating circuit. The voltage-switching control circuit respectively switches the liquid crystal positive voltage and the liquid crystal negative voltage to input to the common driver in different frame stages such that only one of the liquid crystal positive voltage and the liquid crystal negative voltage exists at the same time. Therefore, for the choice of the semiconductor manufacturing process for the LCD driver, the process with only half of the voltage-resistant can be chosen according to the original design of the circuit, and the supplying for the voltage needed by the segment driver and the common driver is unchanged.

    Abstract: The present invention relates to a method of whole-chip electrostatic discharge protection, wherein the chip has a first metallic layer and a second metallic layer, and each surrounds the chip along the trail keeping an appropriate spacing away from the perimeter of the chip separately, and in contrast to the first type semiconductor substrate, a second type semiconductor well is formed below the first metallic layer. The second type semiconductor well, which surrounds the chip along the trail keeping an appropriate spacing away from the perimeter of the chip, can function as a large capacitor to store the discharged electricity. Thereby, the electrostatic discharge protection of the whole chip can be promoted with no increasing chip area needed and without changing the original design and manufacture process of IC.
