摘要： A method provides modeling of surface roughness effect of an electrical conductor. The method includes identifying first protrusions of a first level using an original flat surface of the conductor as a first base surface and determining a first correction factor of the first level using parameters of the first protrusions. The method further includes identifying second protrusions of a second level using the first protrusions and the first base surface as a second base surface, and determining a second correction factor of the second level using parameters of the second protrusions and regarding the second base surface as being a smooth surface, the smooth surface being a surface of the conductor without surface roughness effect. A final correction factor of the conductor is determined by combining the first correction factor and the second correction factor.

摘要： Techniques and mechanisms for mitigating signal deterioration in communications between two circuit boards. In an embodiment, a packaged device accommodates coupling to a first circuit board which, in turn, accommodates connection to a second circuit board. In one such embodiment, an amplifier circuit of the packaged device includes an amplifier circuit which comprises a variable resistor and an active circuit element coupled thereto. The device receives via one of the circuit boards a control signal and a voltage which configure the amplifier circuit to provide an impedance matching for communication between the circuit boards. In another embodiment, the device comprises multiple common gate amplifiers which are variously configurable each to provide a respective impedance matching for communications between a motherboard and a dual in-line memory module.
