Abstract in different language: | Practical design of a voltage reference based on the well-known self-biased Brokaw bandgap core with bipolar-junction transistors (BJTs) is presented. The voltage reference has its own start-up circuit and a voltage regulator, which is capable of operation even under fast input supply voltage transients and its voltage regulation also removes an impact of the Early effect of the BJTs. The voltage reference operates with an external supply voltage from 5 V to 40 V in the temperatures from –50 °C to 200 °C; it occupies layout area of 0.011 mm2 if the 0.35 μm I3T50 ON Semiconductor technology is used. Simulation results show reference voltage of (1.20 ± 0.08) V is generated across process, temperature and supply voltage spread, including components mismatch. |
