<p>A band gap reference circuit comprises a first branch (1) having a first transistor (Q1) and a first temperature-dependent resistive element (SO). A second branch of the band gap reference comprises a second transistor (Q2) having a different size compared to the first transistor (Q1). An output branch (3) comprises a second temperature-dependent resistive element (S1, S2), 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 (S0, S1 S2) comprises a transistor (M2) being arranged in a current path of the respective branch (1, 3) and being controlled such that it operates in a linear region of its characteristics.</p> |
