Özet

This paper presents a low power bandgap reference generator with 193-mV output voltage. The nominal supply voltage is 0.8 V, but the circuit can work with a supply down to 0.65 V. The circuit has been fabricated with a standard 0.18 mu M CMOS technology and achieves a temperature coefficient of 43 ppm/degrees C for temperatures ranging from 0 to 120 degrees C. A sampled-data amplifier consuming 140 nA and a reversed current-mode bandgap scheme draining 350 nA enable the achieved performance.
