ABSTRACT:
A start circuit for a bandgap reference cell using CMOS transistors including a transistor connected between the bandgap reference cell and a differential amplifier in the feedback path to create an offset voltage in the bandgap reference cell when power is first applied, which offset insures the correct operation of the bandgap reference cell, and to turn off after correct operation has been achieved.
