- A low-voltage bandgap reference (BGR) circuit is designed and fabricated
in a 90 nm CMOS technology. To mitigate error resulting from
the mismatch in temperature dependency of the current in the output
current mirror device and that of the BGR core, an output-regulated
current mirror is incorporated. Experimental results show that the
output voltage is 497.2 mV at 258C with a temperature coefficient of
28.3 ppm/8C between 2408C and 808C. The circuit occupies
0.0337 mm2 and dissipates 276.6 pW with a supply voltage of 1.2 V.
