On-Demand Power Supply Current Modification System and Method for an Integrated Circuit

摘要

A circuit that selectively connects an integrated circuit to elements external to the integrated circuits. The circuit includes an input/output element that selectively connects an input/output pin as a function of a power requirement or a signal bandwidth requirement of the integrated circuit. The input/output element includes one or more switching devices that connect the input/output pin to an external element, such as a power supply or external signal path. The input/output element also includes one or more switching devices that connect the input/output pin to an internal element, such as a power network or internal signal line.
