The circuit of the reference voltage of the forbidden band of the drawings

摘要

The invention relates to the references. / p & & p & a voltage reference circuit using a voltage of the forbidden band comprises, in particular, a cell of the forbidden band 52, which comprises two npn transistors 13, 14 branches of the differential pair, to produce a voltage of a spacing difference, and two pnp transistors 7, 8 connected by the issuers and branches of the current mirror circuit in order to constitute the devices of the load for the npn transistors. The cell is associated to a circuit for the reaction of the transistors a load of 10 9, 10, 12, which is connected between the output and the input of the cell. / p & & p & application to voltage sources of precision.
