CMOS BANDGAP REFERENCE VOLTAGE CIRCUITS

摘要

: A CMOS bandgap voltage reference which is temperature stable is disclosed. The large temperaturedependent p-tub resistors of piror art arrangements are replaced with relatively small, temperature stable p+ diffusion resistors. The increase in current level needed to compensate for the decrease in resistor value is provided by a simple cascode MOS circuit located between the ratioing resistors and the VSS potential.
