摘要： A method for extracting a clock in a clock data recovery system is provided. The method includes following steps. First, a serial link transmission data is sampled for a number of times, and a number of pulse signals are generated and sequentially arranged. Then, a mark is inserted after all pulse signals are generated and had been delayed for a predetermined delay time. The predetermined delay time is less than a period between two adjacent pulse signals, and a period between two adjacent pulse signals is divided into two sub-periods by the predetermined delay time. Then, it is checked whether the data status in each sub-period is changed or not, and this operation is repeated for a predetermined number of times. Finally, the clock is extracted when a pulse signal of no data status change within the predetermined number of times is being generated.

摘要： A transmitter for transmitting data in response to N clock signals with the same period T is provided. Every two adjacent clock signals have a phase difference of T/N therebetween. The transmitter includes a clock synthesizer and a multiplexer. The clock synthesizer sequentially generates N select signals in response to level-switch states of the N clock signals, respectively, during the period T. The multiplexer is electrically connected to the clock synthesizer for selecting one of N input data signals to be outputted in response to a corresponding one of the N select signals in turn. A method for transmitting data with eliminated duty-cycle effect is also disclosed.

摘要： A multi-stage lens driving device comprises a lens holder, a lens mounted on the lens holder, a carriage carrying the lens holder in a movable manner, at least one magnet coupled to the lens holder, at least one coil disposed on the carriage and corresponding to the magnet, and at least one yoke disposed at a predefined position of the carriage. Through the magnetic field produced by the magnet and the current action in the coil, the force generated thereof can push the lens holder to move toward a desired position, thereby achieving the effect of focusing or zooming. In addition, through the attraction between the yoke and the magnet on the lens holder, the lens holder may be secured to the predefined position. That is, the lens is firmly secured even when the coil current is shut off, thereby achieving the goal of saving power consumption.

摘要： A data transmission system using a pair of complement signals (STROB/STROB#) as an edge-aligned strobe signal and input/output buffers therein. Several data signals and a pair of STROB/STROB# signals are transmitted from a data output device to a data input device therein. These data signals and the STROB/STROB# signals are edge-aligned and transmitted through the same transmission architecture. The data input device includes several data comparators for generating output signals from the received data signals using the received STROB/STROB# signals as a dynamic reference voltage. In addition, the data input device further includes several comparators and delay elements for generating a pair of non-inverting/inverting latch clock signals from the STROB/STROB# signals. Each of the output signals is sent to two data latch circuits for outputting two latched data based on the latch clock signals.

摘要： A method and system for providing a contact hole between structures for a semiconductor device is disclosed. The method and system comprises etching a resist material on the semiconductor device to expose a surface of the structures; providing an implant to the surface of the structures; and removing the resist material from a gap between the structures. The method and system includes annealing the semiconductor device to cause the implant to adhere to the treated surface; and providing dielectric material within the gap. Finally, the method and system includes etching the contact hole in the gap between the structures. The contact hole can then be etched without damaging the structures. Accordingly, by providing an implant treated surface and then providing an anneal process the implant is bonded to the appropriate portion of the semiconductor structure. Due to the etch difference between the implant treated device and the non-treated surface, it is possible to etch down to the bottom of the semiconductor device without damaging the gate. Since the surface around the gate structure is treated, the etch stop layer etch at a much slower rate. Therefore, there is a much larger process margin for misalignment allowance and the contact size can be larger because the dielectric material and the surface treatment protects the gate area.
