"CMOS Bandgap References With Self-Biased Symmetrically Matched Current–Voltage Mirror and Extension of Sub-1-V Design"09_by Yat-Hei Lam, Member, IEEE, and Wing-Hung Ki, Member, IEEE
Abstract—A series of bandgap references (BGRs) using a self-biased symmetrically matched current–voltage mirror (SM CVM) in reducing systematic offset, thus achieving an excellent line regulation, is presented. By replacing the operational amplifier with a CVM in the feedback loop, current consumption is much reduced. An SM buffer stage that is capable of driving a resistive load with minor degradation in temperature coefficient (TC) and line regulation is also presented. The technique is extended to design a sub-1-V BGR with a TC-cancellation output buffer. All circuits are designed using a 0.35- mCMOSprocess, and experimental results are presented, confirming the analysis.
