Analysis and Design of a CMOS Low-Voltage Bandgap Reference Circuit
Huang Jing-sheng · Microelectronics & Computer · 2006
Current Summing is the basic method to realize low-voltage reference which is different from that of conventional voltage mode. A current generation principle with negative temperature coefficients is analyzed in details. Based on current mode, a brief voltage reference circuit without Operational Amplifier is presented. The maximum output bandgap voltage is about 1.1V, and the total current is within 7μA.
