ABSTRACT:
A semiconductor integrated circuit for a CMOS microcomputer and others having an analog circuit, in which a gate voltage of a transistor for setting a bias current is generated by arranging a diode formed by two islands in a MOS structure and a transistor in series, so as to decrease also a temperature dependence characteristic of the analog circuit. Thereby, the fluctuation of the characteristic of the analog circuit can be restrained despite of fluctuation not only of a power-supply voltage but also of a temperature.
