摘要：Selectable capacitors are used to modify performance characteristics offunctional circuit elements of an integrated circuit (IC). In one embodiment, the
decoupling capacitors are implemented as additional or alternative mounting pads on a
surface of the IC. At least one selectable capacitor is provided for each IC circuit element,such as a logic network, whose operational characteristic(s) is predicted to be and isactually identified as sub-optimal through IC testing, particularly following a processchange, a mask shrink, operation of the IC at higher clock frequency, or the like.Expensive redesign is avoided by selectively coupling capacitors into the IC circuitelement as needed, under control of selector logic that is responsive to control signals.Methods of operation, as well as application of the apparatus to an electronic assemblyand an electronic system, are also described.
