  • A novel CMOS bandgap reference is presented.A negative feedback clamp technique is used which eliminates the offset of Op-Amps and simplifies the design.A regulated cascode configuration is used to improve Power Supply Rejection Ratio(PSRR).It is implemented in SMIC standard 0.18m CMOS process,the results from HSPICE simulation show that the temperature coefficient between-15~70℃ is 10.8ppm/℃,and the PSRR at 10Hz is 74.7dB,the output noise voltage is 148.7V/sqrt(Hz).
