Abstract—This paper proposes a CMOS bandgap reference
(BGR) circuit, which can successfully operate with sub-1-V supply.
In the conventional BGR circuit, the output voltage Vref is the
sum of the built-in voltage of the diode f Vand the thermal voltage
VT of kT=q multiplied by a constant. Therefore, Vref is about
1.25 V, which limits a low supply-voltage operation below 1 V.
Conversely, in the proposed BGR circuit, Vref has been converted
from the sum of two currents; one is proportional to Vf and the
other is proportional to VT . An experimental BGR circuit, which
is simply composed of a CMOS op-amp, diodes, and resistors, has
been fabricated in a conventional 0.4-m flash memory process.
Measured Vref is 518  15 mV (3) for 23 samples on the same
wafer at 27–125C.
Index Terms—Bandgap reference, CMOS, low voltage.
