ABSTRACT:
An integrated circuit assembly includes a voltage level generator, a level shifter, a bandgap reference generator and a voltage regulator. The voltage level generator generates output voltage level signals in response to a supply voltage. The level shifter receives the output voltage level signals from the voltage level generator and generates first and second sets of control signals. The bandgap reference generator receives a reference voltage input and generates a bandgap reference signal. The voltage regulator receives a supply voltage, the bandgap reference signal the first and second sets of control signals from the level shifter and generates a constant output voltage under varying circuit conditions.
