A high-performance bandgap reference with advanced curvature-compensation

A high-performance bandgap reference (BGR) with segmented compensation is proposed in this paper. In order to realize high-order curvature compensation, a voltage proportional to Vbe/ß is used in lower temperature, and a voltage with more positive TC is added in higher temperature. The proposed BGR has been simulated with NEC 0.6µm BCD technology. The temperature coefficient (TC) is 5.4ppm/µC with the temperature ranged from −40µC to 80µC. There is only 0.1mV change in output voltage with supply voltage ranging from 2V to 5V. The power supply rejection ratio (PSRR) is 87dB at 3V supply voltage and room temperature without any filtering capacitor. The maximum power dissipation is only 0.04mW.
