ABSTRACT:
There is disclosed a circuit for generating a reference voltage including first means for lowering the the input bias below an externally applied voltage and reducing first the variation of the voltage level due to the applied voltage, second means for causing the flow of a current depending on the output of said first means to sense the applied voltage state and generating the reference voltage increased by the amount of voltage dropped through the resistance produced according to said current flow to the output terminal of said reference voltage when a fixed constant voltage is applied, and third means for charging and discharging a part of the applied current according to the applied voltage variation of said second means.
