Zusammenfassung:A method and circuit for implementing a level shifter for translating logic signals to output voltage analog levels, and a design structure on which the subject circuit resides are provided. The circuit includes a level shifter resistor divider string of a plurality of series connected resistors, the level shifter resistor divider string is connected between an analog voltage rail and an analog ground. A plurality of level shifter cascaded inverters are connected between respective resistors of the level shifter resistor divider string and an analog voltage rail and an analog ground. An output of the level shifter is programmed by the level shifter resistor divider string connected to the cascaded inverters.
