Abstract
Energy consumption is reduced within an Internet of Things (IoT) device, without degrading operating performance of the corresponding internal circuitry. A first internal supply voltage (VDDa) used to supply the internal circuitry is reduced from a VDD supply voltage to a lower voltage during an idle state, thereby reducing leakage currents in the internal circuitry. The first internal supply voltage (VDDa) may be reduced to a voltage that is one threshold voltage (Vtp) lower than the VDD supply voltage. A second internal supply voltage (VSSa) used to supply the internal circuitry is increased from the VSS supply voltage to a voltage higher than the VSS supply voltage during the idle state, thereby further reducing leakage currents in the internal circuitry. The second internal supply voltage (VSSa) may be increased to a voltage that is one threshold voltage (Vtn) higher than the VSS supply voltage.
