Abstract
An integrated circuit is provided, which includes first, second and third power supply conductors. The second power supply conductor has a higher voltage than the first power supply conductor, and the third power supply conductor has a higher voltage than the second power supply conductor. A high voltage power supply decoupling capacitor is coupled between the first and third power supply conductors. A low voltage power supply decoupling capacitor coupled between the first and second power supply conductors. A voltage reducer is coupled between the second and third power supply conductors. A plurality of semiconductor devices is biased between the first and second power supply conductors.
