Abstract:
1. An integrated circuit comprising: a first module in a first independent power supply zone; a second module, independent of the first module, in a second independent power supply zone; a first internal power supply bus that operates to receive electrical power from a power supply circuit and communicate first electrical power to the first module and not to the second module, where the first electrical power is characterized by a first set of power characteristics that comprises a first voltage level and a first amount of voltage variability; and a second internal power supply bus, independent of the first internal power supply bus, that operates to receive electrical power from a power supply circuit and communicate second electrical power to the first module and the second module while the first internal power supply bus is communicating the first electrical power to the first module, where the second electrical power is characterized by a second set of power characteristics that comprises a second voltage level and a second amount of voltage variability; where the first voltage level and the second voltage level are substantially similar, and the first amount of voltage variability is different from the second amount of voltage variability.
