A low power, offset compensated, CMOS only bandgap reference in 22 nm FD-SOI technology

In this paper a very low supply voltage Bandgap Voltage Reference Circuit (BGR) has been presented. A temperature coefficient of 35 ppm/°C is achieved with the all-MOSFET based circuit that operates at a minimum supply voltage of 600 mV and consumes a total power of 9.5 mW. Chopping technique has been employed to eliminate the error at the output caused by the DC offset of the amplifier. The presented circuit has been designed in a 22 nm Fully Depleted Silicon on Insulator (FD-SOI) CMOS process.
