Dear all,

I've a question about BGR.

In attatched figure, it is from

A. P. Brokaw, "A simple three-terminal IC bandgap reference," IEEE Journal of Solid-State Circuits, vol. 9, pp. 388 - 393, December 1974.

and a paper says,

A simple current mirror takes the difference of the collector currents of Q2,Q3.

This different current drives Q1.

The sense of the signal to Q1 drives Q2,Q3 to minimize the collector current difference.(negative feedback)


But I cannot understand. would you please give me some detail?

Regards.
