Abstract
A bandgap reference circuit 30 includes a current generation circuit 32, a voltage generation circuit 34 connected to current generation circuit 32, and a compensation circuit connected to current generation circuit 32 and voltage generation circuit 34. Current generation circuit 32 sources a current to voltage generation circuit 34 which translates the current into a voltage. Compensation circuit 36 monitors current generation circuit 32 and provides a supplemental current to voltage generation circuit 34. Voltage generation circuit 34 receives the supplemental current and translates it into a supplemental voltage. The summation of the voltage produced by the current received by current generation circuit 32 and the supplemental voltage produced by the supplemental current received by compensation circuit 36 produces a stable reference voltage.
