The integrated circuit includes two transistors having the same conductivity type (PMOS), which are connected in parallel between a terminal (A) having a potential (Vdd) and earth. The first transistor (Q1) has it's source connected to the base of a bipolar transistor (T1) whose emitter is connected to the terminal (A). The second transistor (Q2) has it's source connected directly to the terminal (A) so that it's gate-source potential is always maintained higher than that for the first transistor (Q1). If the dimensions of the two transistors are correctly chosen their currents will decrease with temperature at different rates and the intersection of the two curves indicate any desired temperature. |
