摘要： A method for testing a printed circuit board to determining the dielectric loss associated with the circuit board material relative to a standard. Dielectric losses in the material generate heat when a high frequency electronic signal, such as a microwave frequency signal, is communicated through a microstrip that is embedded within the printed circuit board. The temperature or spectrum at the surface of printed circuit board is measured and compared against the temperature or spectrum of the standard to determine whether the material under test is acceptable. While various temperature measurement devices may be used, the temperature is preferably measured without contacting the surface, such as using an infrared radiation probe.

摘要： Embodiments of the invention include a common mode cancellation circuit and method for correcting signal skew in a differential circuit. According to one embodiment, an op amp circuit is used to correct the mismatch between transmission line lengths in the differential circuit. The CMCC can be embodied as an ASIC and added on to an existing differential signaling systems to correct and compensate for board wiring skew or other causes of phase misalignment. The result is restoration of the cross-over intersection of the plus and minus signals of the differential pair closer to the common voltage level point, as if the signals had been in phase.
