BAND-GAP REFERENCE VOLTAGE GENERATOR FOR LOW VOLTAGE OPERATION AND HIGH PRECISION

摘要

The present invention is a low voltage high accuracy by also relates to a bandgap reference voltage generator, a low voltage high precision band gap reference voltage generator according to the invention, respectively connected in parallel with the resistance in the bipolar transistor to minimize the voltage drop across the width, and the output resistance change to is characterized in that a temperature variable is to provide a stable voltage reference, independent of the temperature change at a low power supply voltage by to have a value of zero. In addition, low-voltage high precision band gap reference voltage generator according to the present invention is capable of providing an accurate reference voltage, by minimizing the rate of change of the reference voltage due to the offset noise from the switching of the input voltage and the output voltage at the output terminal of the feedback amplifier and that is characterized. ; Low-voltage, the reference voltage, a transistor, a resistor, a voltage modulation, the switching
