Techniques for performing frequency compensation of common-mode feedback loops for differential amplifiers are disclosed. The inner guide can be longitudinally extended and axially rotated relative to the outer guide. The molten material is pushed with a plunger through a gate and into a tool cavity corresponding to the part. In one embodiment, the first computing element and the second computing element issue substantially similar instruction streams to one of the local mass storage devices. A video decoder may receive a bitstream that includes the first and second NAL units.
