| Abstract: | A low-power low-voltage bandgap reference using the peaking current mirror circuit with MOSFETs operated in the subthreshold region is presented. A demonstrative chip was fabricated in 0.35 /spl mu/m CMOS technology, achieving the minimum supply voltage 1.4 V, the reference voltage around 580 mV, the temperature coefficient 62 ppm//spl deg/C, the supplied current 2.3 /spl mu/A, and the power supply noise rejection ratio of -84 dB at 1 kHz. |
