Abstract :
This paper presents two novel implementations of the current-mode band-gap reference (BGR) which support the very low supply voltages of the near future CMOS technologies, without resorting to special devices. Moreover, the problem of the start-up of low-voltage BGRs is discussed and a simple solution which guarantees correct start-up over process, supply voltage and temperature variations is proposed. The band-gap references were implemented in a conventional 0.35 μm. CMOS technology and provides an output voltage of about 500 mV
