Analysis and Design of High Performance Bandgap Refernce
Honghui Deng · Modern Electronics Technique · 2008
All the major non-ideal factors in CMOS bandgap reference and the ideal compensation techniques are proposed.According to the analysis,a precise bandgap reference based on SMIC 0.35 μm CMOS technology had been designed and post-layout simulation shows that the temperature coefficient of the reference is 3.4 ppm/℃ over-40～125 ℃ and the supply rejection ratio is 85 dB for 3.3 V supply.The proposed bandgap circuit had been applied to a 14 bit D/A converter and the D/A converter had past the test.
