A Novel BiCMOS Current-Mode Bandgap Reference

Abstract:

In this paper, a novel BiCMOS current steering bandgap is presented, which includes reference core, start-up circuit, and output circuit, of which the reference core is used to produce the temperature-stable current, the start-up to start up the reference core when powered on, and the output circuit to proportionally transport the reference current to other cells on the same chip. Compared to the traditional voltage-mode bandgap reference, because of the adoption of the current-steering mode, the reference proposed in this paper, has the merits of being immune to variation of the power supply, minimum transport consumption, better matches, temperature stability, smaller area, auto-startup, and so on, which are specially needed in AD/DA application. The simulation shows that the proposed current-mode reference circuit has full temperature range coefficient of 8.9ppm, which is better than that of the traditional voltage-and current-mode reference circuits.
