  • Abstract
    A curvature-compensated current mode bandgap reference with improved PSRR is presented. The circuit takes advantage of a simplified straightforward implementation of the curvature compensation method, the reference achieves a temperature coefficient of 7ppm/ degC over the temperature range of -20degC to +80 degC. And by using negative feedback to generate a regulated supply, the power supply rejection ration (PSRR) of the proposed circuit can be increased up to 90dB at 10kHz.The circuit is designed using 0.8 mum BiCMOS technology and silicon area is 1.07 times 0.92 mm2
