Design of an Improved Current Summing Reference
Shanli Long · 2006
A CMOS band-gap current summing reference is designed,which is self-biasd with a cascode structure.Hspice simulation with a Chart CMOS 0.35 μm and 5 V power supply shows that,within(-40～85 ℃),the temperature coefficient is 15.2×10~(-6)/℃,and the power supply restrain ratio is-51.8 dB.
