Patent abstract
A non-linearity compensation circuit and a bandgap reference circuit using the same for compensating non-linear effects of a reference voltage are provided. In the non-linearity compensation circuit, the reference voltage is transformed into a temperature independent current. A current mirror mirrors the temperature independent current for biasing a bipolar junction transistor (BJT). Further, two resistors are used for estimating a non-linear voltage, so as to compensate the reference voltage.
