| titleOfInvention | Bicmos current-mode reference circuit |
| abstract | A BiCMOS current-mode reference circuit comprises a reference core circuit (402), a startup circuit (401), and a reference current output circuit (403). The reference core circuit (402) comprises three parts: a current mirror circuit (404), a positive temperature coefficient current generation circuit (405), and a negative temperature coefficient current generation circuit (406). The current mirror circuit (404) is used to generate matching branch currents. A positive temperature coefficient current and a negative temperature coefficient current are added in specified proportions to obtain a reference current at normal temperature when the temperature coefficient is zero. The startup circuit (401) is used to start the reference core circuit (402) during power-up. The reference current output circuit (403) is used to output the reference current generated by the reference core circuit (402) in proportions. Compared with a traditional voltage-mode reference circuit, the BiCMOS current-mode reference circuit has the advantages such as immunity to a direct-current voltage drop of a power supply network, small transmission loss, good matching performance, high temperature stability, a small chip area, and automatic startup on boot, and is especially applicable to scenarios where an analog-to-digital/a digital-to-analog convertor has strict requirements on reference signals. |
