Abstract: Embodiments disclosed herein relate to an amplifier stage or circuit for providing a signal boost. The circuit includes an emitter-follower pair and a cross coupled differential pair. The cross coupled differential pair provides a feedback signal that provides a boost to a signal output by the emitter follower pair. In some embodiments, a capacitor of the cross coupled differential pair may be adjustable in order to vary the amount of boosting provided. In other embodiments, a current source of the cross coupled differential pair may be adjustable in order to vary the amount of boosting provided.

Abstract: An edge connector suitable for attachment with a printed circuit board. The edge connector comprises a body composed of a plastic resin, the body defining a first end that is configured to operably attach to a portion of a printed circuit board and a second end configured to operably connect to a slot in a host device and a plurality of conductive traces and contact pads defined on a portion of a surface of the body, the traces being configured to electrically connect with corresponding traces defined on the printed circuit board.
