Abstract:
A device that includes a voltage supply unit and an integrated circuit, the device is characterized by including a voltage sampling circuit adapted to sample voltage levels at multiple sampling points within the integrated circuit, to provide multiple sampled voltages, wherein the multiple sampled voltages reflect the voltage drops; and wherein the voltage supply unit is adapted to adjust a supply voltage provided to the integrated circuit in response to at least one sampled voltage. A method for voltage drop compensation; the method includes providing a supply voltage to an integrated circuit; the method is characterized by sampling voltage levels at multiple sampling points within the integrated circuit, to provide multiple sampled voltages, wherein the multiple sampled voltages reflect the voltage drops; and adjusting a supply voltage provided to the integrated circuit in response to at least one sampled voltage.
