Abstract :
This paper proposes the startup circuit for a low voltage CMOS bandgap reference circuit. The all MOS scalable voltage bandgap reference (BGR) circuit has been designed and simulated using a standard 65 nm CMOS technology. The proposed startup circuit is simple, smaller in size and uses the feedback mechanism. The BGR circuit provides 661.54 mV of the voltage reference and 9 μA of the current reference with the temperature sensitivity of 4.23 ppm/°C. The total power consumption of the BGR and the startup circuitries are 243 μW and 148 nW respectively.
