Abstract:
A circuit includes a power switch and a level shifter. The level shifter has a node and an assistant circuit. The node is configured to control the power switch. The assistant circuitry is coupled to the node and configured for the node to receive a first voltage value through the assistant circuit. The first voltage value is different from a second voltage value of an input signal received by the level shifter.
Abstract:
A method of manufacturing a photomask is described. The graphic data of the photomask are provided, and than an optical proximity correction is performed to the graphic data. A process rule check is then performed to the graphic data with the optical proximity correction. When at least one failed pattern not passing the process rule check is found in the graphic data, a repair procedure is performed only to the failed pattern so that the failed pattern can pass the process rule check. The patterns of the photomask are then formed according to the corrected and repaired graphic data.

Abstract:
A computing device and an automobile controlling method stores identification information in an electronic tag of authorized communication devices and a memory of the computing device. The identification information of an electronic tag of a communication device is obtained and a door of an automobile is unlocked if the obtained identification information matches identification information stored in the memory.
Abstract:
One of the advantages of direct frequency synthesis technique (e.g., flying-adder architecture) is its capability of generating arbitrary frequency by utilizing the time-average-frequency concept. In the clock output of the direct frequency synthesizer, instead of one type of cycle, there are two types of cycles. Unlike the conventional one-type-cycle clock wherein clock energy is concentrated at its designed frequency, Time-Average-Frequency based clock spreads some of its energy into spurious tones, which could be harmful to certain applications. The spurious tones are caused by the periodic carry sequence generated from a fractional part accumulator inside the frequency synthesizer. The invention suggests a method and an apparatus to break this periodicity and convert the spurious tones into broadband noise.
Abstract:
Disclosed is a printed circuit board structure which is manufactured by providing a core board, forming an inner circuit layer on the core board surface, forming a bonding pad on the inner circuit, forming a ring-shaped anti-etching layer on the bonding pad, forming an anti-soldering insulation layer on the ring-shaped anti-etching layer and the bonding pad, and forming an opening to expose a part of the bonding pad, wherein the radius of the opening is shorter than the radius of the ring-shaped anti-etching layer, and the bonding pad surface is free of concave. The described structure may prevent the solder extending along the bottom void of the anti-soldering insulation layer to other regions.
Abstract:
An interpolation circuit adapted to receive a plurality of inputs is provided. The inputs include a first input group and a second input group. The interpolation circuit includes a first selecting channel, a second selecting channel, and an interpolation unit. The first selecting channel receives the first input group and outputs a first input of the first input group according to a selecting signal. The second selecting channel receives the second input group and the first input and outputs a second input of the second input group according to the selecting signal. The first selecting channel and the second selecting channel respectively output the first input or the second input. The interpolation unit is coupled to the first selecting channel and the second selecting channel, and receives the first input and the second input, and accordingly performs an interpolation to output an interpolation result.
