摘要： PROBLEM TO BE SOLVED: To provide a constant current circuit having a small area.SOLUTION: Constant current I1 of a constant current circuit is reduced by on-resistance of a high resistance value of a NMOS transistor 23 operating in a strong inversion region/non-saturation region, without depending on a resistance of a high resistance value. Accordingly, the area of the NMOS transistor 23 is smaller than that of a resistance having the same resistance value as that of on-resistance of the transistor 23 to reduce the area of the constant current circuit.

摘要： PROBLEM TO BE SOLVED: To provide a constant current circuit capable of being operated at a lower supply voltage.SOLUTION: A constant current circuit can be operated when a power supply voltage VDD is higher than the addition voltage of the voltage Vds 10 between a drain and a source of a depletion type NMOS transistor 10 and voltage Vgs 15 between a gate and a source of an NMOS transistor 15. Since, as the power supply voltage VDD of the constant current circuit, the addition voltage of one voltage between the drain and source and one voltage between the gate and source becomes necessary and no addition voltage of one voltage between the drain and source and two voltages between the gate and source becomes unnecessary, the minimum operation supply voltage of the constant current circuit becomes low.

摘要： PROBLEM TO BE SOLVED: To provide a constant current circuit with a small area.SOLUTION: Without employing a resistor having a high resistance value, a constant current IREF of a constant curent circuit is reduced by an on resistance having a high resistance value of an NMOS transistor 13 operated in an unsaturated region of a strong inversion region. Since the NMOS transistor 13 has a smaller area than a resistor having the same resistance value as its on resistance, the area of the constant current circuit may be reduced.
