Abstract
PURPOSE: To secure the optional setting for the temperature coefficient of the constant current and thus ensure the high-accuracy control by forming the IC formation base resistance deciding the inflow current value and the sucking current value of the current inflow circuit with different diffusion and sheet resistances.
CONSTITUTION: The current supply circuit is provided to decide the inflow current value of the current inflow circuit which doubles the current inflow circuit and the current sucking circuit by IC formation base resistance R1 as well as to decide the sucking current value of the current sucking circuit by IC formation base resistance R2 each. Here resistances R1 and R2 are composed of the base resistance featuring the sheet resistance including the difference diffusion resistances plus ion injection resistances. And the temperature coefficient of the constant current which is decided through the subtraction among different absolute value of the temperature coefficients of resistances R1 and R2 is set optionally to the plus, minus or zero value to secure the high-accuracy control.
