Abstract
An integrated circuit supplied by a rail-to-rail power supply voltage includes a multi-level stack voltage generator configured to partition the rail-to-rail power supply voltage into one or more reduced supply voltages each having a voltage value between positive and negative power supply voltages of the rail-to-rail power supply. The reduced supply voltages and the positive and negative power supply voltages being configured in series to form a stack of circuit layers. The integrated circuit further includes a core circuit including core circuit units coupled in a circuit layer or coupled between two or more circuit layers. Each core circuit unit is coupled to at least one of the reduced supply voltages. The core circuit units are coupled in the stack of circuit layers to form a serial connection of core circuit units between the positive power supply voltage and the negative power supply voltage.
