The subject matter of this disclosure relates to a flexible circuit for carrying a signal between electrical components that includes boosting circuitry for mitigating the effects of signal degradation. More particularly the flexible circuit can carry a signal between a main logic board and an input/output board supporting input/output ports of a portable electronic device. The flexible circuit can be configured with bends in order to meet packaging constraints such as avoiding contact with components obstructing a direct path between connectors of the electrical components. Additional bends can also be included in the flexible that facilitate the assembly of the portable electronic device.
