Abstract
A matched load for an unloaded terminating end of a signal transmission line on a printed circuit wiring board avoids reflecting pulses back down the line. A non-reflective attenuation region is provided under the unloaded terminating end, such region being wedge-shaped and doped to a reduced resistivity, and situated in the silicon substrate of the board. Data pulses at the unloaded terminating end of the transmission line, modulated at the selected operating frequency of the board, are substantially attenuated by the doped region.
