Abstract
An apparatus comprises one or more A-type resistance segments, wherein each A-type resistance segment comprises one or more A-type switches, at least one A-type linear resistor coupled to the one or more A-type switches, at least one A-type tunable header unit coupled to the one or more A-type switches, and at least one A-type tunable footer unit coupled to the one or more A-type switches; one or more B-type resistance segments, wherein each B-type resistance segment comprises one or more B-type switches, at least one B-type linear resistor coupled to at least a proper subset of the one or more B-type switches, at least one B-type tunable header unit coupled to the one or more B-type switches, and at least one B-type tunable footer unit coupled to the one or more B-type switches; and wherein second terminals of the A-type linear resistors and the B-type linear resistors are coupled together.
