Title: Power source circuit
Inventor: TANAKA MIKITO
IPC: G05F1/56
Filed: 1988-05-30
Abstract: PURPOSE:To change the temperature feature of an output voltage as well by determining the feedback quantity of the output voltage for a differential amplifier with the ratio of first and second resistances, and changing the current quantity of a constant current source and the ratio of the first and second resistances. CONSTITUTION:When the currents applied to FETs 1 and 2 change, the voltage of the non-inverted input terminal of a differential amplifier 4 changes, and the voltages to be impressed on the FETs 1 and 2 also change. However, since the voltage fluctuation with respect to the temperature change of the FETs 1 and 2 does not change, a change rate with respect to the voltage impressed on the FETs 1 and 2 changes. The amplifier 4 operates so that the voltages of inverted and non-inverted inputs may be equal, and controls the gate voltage of an FET 5 so that the reference voltage and the voltage of the contact point between resistances 6 and 7 may be equal. When the resistance values of the resistances 6 and 7 are respectively set at R6 and R7, the voltage of an output terminal 8 is (R6+R7)/R7 ties of the reference voltage, and the temperature characteristic is the same times as above. Thus, by regulating the ratio of the resistances 6 and 7, the temperature characteristic of the power source circuit can be made variable.
