IEEE（1998） A 1.1-V Current-Mode and Piecewise-Linear
Curvature-Corrected Bandgap Reference
by
Gabriel A. Rincon-Mora and Phillip E. Allen
Abstract—A low-voltage, micropower, curvature-corrected
bandgap reference is presented that is capable of working
down to input voltages of 1.1 V in a relatively inexpensive
process, MOSIS 2 m technology. This is a vanilla N-well
complementary metal–oxide–semiconductor process technology
with an added P-base layer. Second-order curvature correction
for this reference is accomplished by a versatile piecewise-linear
current-mode technique. The 0.595-V precision reference
achieved a line regulation performance of 408 ppm/V for input
voltages between 1.2 and 10 V. The circuit only used 14 A
of quiescent current flow.
Index Terms—Bandgap, curvature correction, low voltage, micropower,
reference. |
