To meet the demand of the low voltage equipment,a low-voltage CMOS bandgap circuit is designed.The body-driven technique of the amplifier is adopted,thus enlarging the region of common-mode input voltage.The circuit adopts the resistive subdivision so as to adjust the ratio of the resistors for getting the reference voltage.This design was simulated by the TSMC 0.35 μm CMOS technology.The operating voltage of the circuit is 1 V,and it provides 550 mV output reference voltage.The temperature coefficient is 19×10-6/℃ within the temperature range from-40 ℃ to 120 ℃.
