The different illustrative embodiments provide an apparatus, a system, and a method for managing a portal. A multi-component jet consists of two or more liquids. The memory is mounted to the block so as to be inclined at substantially 45 with respect to a rear surface and a bottom surface of the case. For example, a delta-sigma modulator may be constructed with an inner loop having a sixth order and an outer loop having a second order, in which the stability of the delta-sigma modulator is proportional to that of a second order.
