Abstract:
The present invention provides for a device to reduce the voltage swing for control signals. An input signal with a maximum potential of DVDD and minimum potential of AVSS is level shifted to a maximum potential of AVDD and a minimum potential of AVDD-DVDD. A series of control signals are generated from the level shifted input signal by standard logic cells. The shifting of the input signal reduces the voltage swing for the control signals. These control signals are then used to drive a device operating at a potential of AVDD.
