Abstract: |
This invention belongs to band gap basic power field, which is characterized by adding two current branches on current power and dividing two triodes integration injection current and fetch current to change their temperature properties and to change output basic voltage temperature property to achieve three basic voltage local maximum points in whole work range to make the output voltage basic temperature first degree derivative as zero. |
