INTERNAL CMOS REFERENCE GENERATOR AND VOLTAGE REGULATOR

摘要

An embodiment of the present invention includes a reference generator and voltage regulator circuit (110) for deriving a reference signal having a reference voltage from a system voltage source having a system voltage level wherein the reference voltage level remains substantially unaffected by variations in the system voltage level and variations in temperature, the circuit (110) including a voltage reference sub-circuit (112), a voltage regulator sub-circuit (114), a voltage translator sub-circuit (116), a filter sub-circuit (118) and an output sub-circuit (120).
