Abstract: PURPOSE: To reduce hysteresis with respect to temperature by making a voltage drop between both the ends of a 1st resistor proportional to a difference between 1st and 2nd forward voltage drops and making the temperature coefficient of a voltage drop proportional to a difference between 1st and 2nd temperature coefficients. CONSTITUTION: In applied design, the junction size of a transistor(TR) Q1 and a diode D1 can be selected so that the voltage temperature coefficients of the TR Q1 and the diode D1 are substantially the same in a different state of their junction voltage. In this case, voltage between both the ends of a resistor R1 has a voltage temperature coefficient equal to a slightly positive or negative value. Thereby a temperature compensation current Iref' can be obtained and the current is determined by a difference of the seletected temperature coefficients between the diode D1 and base-emitter junction. A current Iref is also temperature-compensated and has no dependency on a joint voltage temperature coefficient or has a prescribed controlled dependency.
