摘要： A signal transmission apparatus includes two circuit layers. First and second ground sheets are arranged in the two circuit layers respectively. A third ground sheet is arranged between the two circuit layers. A differential pair includes a transmission line arranged between the first and third ground sheets and a transmission line arranged between the second and third ground sheets. The first to third ground sheets have same electric potential. Projections of the first and second ground sheets on the third ground sheet superpose a border of the third ground sheet. The third ground sheet is formed by extending the border along a signal transmission direction. A vertical distance between the first and second transmission lines is twice as each of a vertical distance from the first ground sheet to the first transmission line and a vertical distance from the second ground sheet to the second transmission line.

摘要： A simulation system for producing equivalent circuits reads data corresponding to a tabular W element format in a storage device, and adds data of the tabular W element format file using interpolation algorithm. A frequency-dependent transmission matrix is transformed into an N-port network matrix describing electrical properties of a multi-input and multi-output network. An N-port network matrix is transformed into a S-parameter matrix. A range of frequency of a s-parameter is determined and numbers of pole-residue, times for recursion and durable maximum system errors in the equivalent circuit is also determined. A vector fitting algorithm is performed and a rational function matrix composed with s-parameters is produced, to produce a general SPICE equivalent circuit based on the generated rational function matrix.

摘要： An overdrive topology structure for transmission of a RGB signal includes a signal sending terminal, a signal receiving terminal, and a transmission line to transmit the RGB signal from the signal sending terminal to the signal receiving terminal. The transmission line is divided into a number of section transmission lines. A node is formed between every two section transmission lines. An impedance of a first section transmission line approaching to the signal sending terminal is less than an impedance of a second section transmission line approaching to the first section transmission line to overdrive the RGB signal at a first node between the first and second section transmission lines. At least one node except the first node is grounded via a resistor. An equivalent resistance of the resistor is equal to a resistance of the first resistor.

摘要： A multilayer printed circuit board (PCB) includes a plurality of signal planes, two reference planes, a signal via, and a stitching via. The signal via passes through all planes for a signal trace flowing therethrough. The stitching via is defined near the signal via and electrically connects to one of the reference plane. The stitching via serves as a stitching capacitor, to reduce the area of the signal current flows in the PCB, even to control crosstalk and lower the noise on the PCB. It is of advantage that the stitching via is simple to manufacture and very suitable for mass production.

摘要： A simulation system and method for generating equivalent circuits compatible with HSPICE reads data corresponding to N-port network system format in a storage device, and obtains S-parameter matrixes from the N-port network system. S-parameters in the S-parameter matrix that satisfy passivity are checked, and an interpolation algorithm to supplement S-parameters with passivity when some S-parameters not satisfy passivity is performed. Numbers of pole-residue, times for recursion and a tolerant system error of a rational function are generated for determining S-parameters. A rational function matrix composed of S-parameters is generated by performing a vector fitting algorithm, and an equivalent circuit is generated compatible with HSPICE format based on the generated rational function matrix.

摘要： A direct current compensation method for S-parameter rational functions reads S-parameters f(sk), which are generated at given frequency sk, from a storage unit. An S-parameter, which is generated at frequency sk=0 is supplemented into the S-parameters f(sk), upon the condition that there is no S-parameter which is generated at the frequency sk=0. An S-parameter ration function is generated according to the S-parameters f(sk). A DC level of the S-parameter rational function is compensated to generate a compensated S-parameter rational function.

摘要： A printed circuit board includes a first signal layer, a second signal layer, a plurality of transmission lines respectively including first segments laid in parallel on the first signal layer and second segments laid in parallel on the second signal layer, and a plurality of vias, each via connecting the first segment with the second segment of a corresponding transmission line. One of the plurality of transmission lines has the first segment positioned in the middle of an array defined by the first segments of the plurality of transmission lines, and a second segment positioned in an outmost position of an array defined by the second segments of the plurality of transmission lines. The printed circuit board reduces the possibility of false action of electronic components coupled to transmission lines, which is caused by the crosstalk between transmission lines.
