发明名称 Reference voltage circuit with positive temperature compensation
摘要 A circuit for producing a reference voltage, particularly for a voltage regulator, has a current source that produces the desired reference voltage across a string of components. The current source is controlled by a differential amplifier that receives inputs that vary with chip temperature. The differential amplifier increases the reference voltage when the chip temperature increases. When the voltage regulator is used with an FET memory, the increase in the regulator voltage with temperature helps to compensate for an increase in the rate that FET storage cells lose the charge that represents data.
