Abstract
- Sometimes, the high-resolution A/D or D/A converter all need a high precision reference, the voltage of reference will determine the precision of the conversion result. In whole system, it always requires that the conversion result should be in a specified range in a wide temperature range. In order to release the variation range of conversion result, it requires that the temperature coefficient of reference should be very small. In this paper, it introduces one higher order compensated band-gap reference, it uses the current $\mathrm{I}_{\mathrm{b}}$ from the existing structure to compensate the higher-order voltage of $\mathbf{V}_{\mathrm{BE}}$ . In this way, the temperature coefficient of this Band-Gap Reference will be less than 1ppm/°C in theory.
