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 μm CMOS technology, achieving the minimum supply voltage 1.4 V, the reference voltage around 580 mV, the temperature coefficient 62 ppm/°C, the supplied current 2.3 μA, and the power supply noise rejection ratio of -84 dB at 1 kHz.
