    摘要: An equalizer includes a first delay module, a second delay module, a first amplitude module, a second amplitude module, and a combining unit. The first delay module receives a first signal and delays the first received signal for a preset period, and the first amplitude module transfers the first delayed signal to transmit a first weighted signal with a first peak amplitude. Similarly, the second delay module receives the first delayed signal and delays the second received signal for the preset period, and the second amplitude module transfers the second delayed signal to transmit a second weighted signal with a second peak amplitude. The combining unit combines an input signal and the first and the second weighted signals together to generate an equalized signal.

    摘要: In a method for analyzing a signal group delay of a printed circuit board (PCB) using a computing device, the computing device connects to a signal measuring device that measures S-parameters from a pair of data signal line and clock signal line of the PCB. The method analyzes a differential loss coefficient of the data signal line and the clock signal line based on the S-parameters, and calculates a first signal delay of the data signal line and a second signal delay of the clock signal line according to the differential loss coefficient. The method further analyzes a signal group delay of the PCB according to the first signal delay and the second signal delay, and displays the signal group delay on a display device if the signal group delay does not satisfy a PCB design specification.

    摘要: In a method of managing process factors that influence electrical properties of printed circuit boards (PCBs), n process factors are arranged in an order according to different influence to one kind of electrical property of the PCBs. The different influence is determined by first experiments designed using the Taguchi method. M process factors that have important influence to the electrical property are obtained from the n process factors according to the order to design second experiments. A computing formula for the electrical property is fitted using the m process factors according to simulated results of the second experiments, and a variation range of each of the m process factors is computed according to the computing formula.

    摘要: A computing device and a method reads a circuit board layout file from a storage device, and selects a first signal transmission line from circuit board layout file as a target line. The computing device and method computes a distance between the target line and the aggressor line corresponding to each unit sample length. If the distance is more than or equal to a height of a sample region, the computing device and method defines the height of the sample region as a crosstalk space between the target line and the aggressor line corresponding to a unit sample length. Otherwise, if the distance is less than the height of the sample region, the computing device and method defines the distance as the crosstalk space between the target line and the aggressor line corresponding to the unit sample length.

    摘要: In a method of optimizing parameters of electronic components on printed circuit boards (PCBs), a first experiment table for m variables of one type of parameter of P electronic components on a PCB is designed using n values of each variable and the RSM. P EHs of each first experiment are obtained by simulating, and P EH empirical formulas are computed according to the P EHs. A second experiment table for the m variables is designed using n′ values of each variable and the full factorial design, and P EHs of each second experiment are computed using the P EH empirical formulas. Experiments, all the P EHs of which are greater than 1, are filtered from the second experiment tables, and an average EH of each filtered experiment is computed to pick an experiment the average EH of which is the greatest. The values of the m variables in the picked experiment are considered as optimized.

    摘要: A differential signal transmission device transmits N differential signal pairs from a differential signal generator to a number of receiving terminals. The N differential signal pairs include N positive signals and N negative signals. The N positive signals are clustered at a first positive clustering point. The first positive clustering point is connected to a second positive clustering point via a first matching resistor. The second positive clustering point is grounded via a first grounding resistor, and outputs a number of positive signals to the number of receiving terminals respectively. The N negative signals are clustered at a first negative clustering point. The first negative clustering point is connected to a second negative clustering point via a second matching resistor. The second negative signal clustering point is grounded via a second grounding resistor, and outputs a number of negative signals to the number of receiving terminals respectively.
