Abstract
A band gap reference circuit comprises a first branch () having a first transistor (Q) and a first temperature-dependent resistive element (S). A second branch of the band gap reference comprises a second transistor (Q) having a different size compared to the first transistor (Q). An output branch () comprises a second temperature-dependent resistive element (S, S), that second temperature-dependent resistive element being coupled to an output terminal (Vref). At least one of the first and second temperature-dependent resistive elements (S, S, S) comprises a transistor (M) being arranged in a current path of the respective branch () and being controlled such that it operates in a linear region of its characteristics.
