(57) Abstract 1st common terminal (2), 2nd common terminal (4), 1st joint terminal (6) and 2nd joint terminal (8): The 1st joint terminal the 1st semiconductor junction to which (6) and the 2nd common terminal (4) is jointed in series between (10) and the 1st resistor (12): The 1st common terminal (2) and the 2nd joint terminal (8) with the 2nd resistor which is jointed between (16): The 2nd joint terminal (8) with the 2nd common terminal the 2nd semiconductor junction to which (4) is jointed between (14): The 1st common terminal the 3rd semiconductor junction to which (2) and the 1st joint terminal (6) is jointed between (18): Output (26), reversal entry (24) and non reversal entry (22) it has, one entry of reversal and non reversal entry is jointed by the 1st joint terminal (6), entry of other things possesses the 2nd joint terminal (8) the differential amplifier which is jointed (20), the 1(2) and one of the 2(4) common terminals the differential amplifier (20) output (26) is reference voltage source in order Drive the constant current source which is jointed. It is possible to designate the temperature coefficient of total electric current I1+I2 as null. Total electric current is reflected in the current source transistor, the current source transistor stability supplies electric current vis-a-vis temperature.
