Abstract
Exemplary techniques for providing an embedded preemphasis circuit and/or a deemphasis circuit in a printed circuit board (PCB) or other circuit device are disclosed. In particular, a technique for preemphasizing and/or deemphasizing transmitted signals in a PCB-based circuit is provided. The technique may be realized as a preemphasis circuit for preemphasizing a signal being transmitted from a signal source to a signal destination. The preemphasis circuit comprises a printed circuit board (PCB), a resistor embedded in the PCB and having a first terminal electrically connected to the signal source and a second terminal electrically connected to the signal destination, and a capacitor embedded in the PCB and having a first terminal electrically connected to the signal source and a second terminal electrically connected to the signal destination.
