APPARATUS AND METHOD FOR HIGH SPEED SIGNALS ON A PRINTED CIRCUIT BOARD

摘要

In some embodiments, an apparatus includes a printed circuit board substrate, a copper signal line disposed on the printed circuit board substrate, and a nonlinear transmission structure coupled to the copper signal line, wherein the nonlinear transmission structure is configured to sharpen a wavefront of a high speed signal pulse on the copper signal line. In some embodiments, the nonlinear transmission structure may include a voltage dependent dielectric layer on the printed circuit board substrate. In some embodiments, the voltage dependent dielectric layer may include a plurality of varactors positioned at a receiving end of the signal line.
