Abstract
A reference current circuit includes: a current mirror circuit for supplying Iout based on Iin; an E-mode MOS including a drain that supplies Iout, a gate connected to the drain, and a grounded source; a first D-mode MOS including a gate terminal connected to the gate terminal of the E-mode MOS, and generating Vref; a voltage dividing circuit for supplying a divided voltage (Vdiv) of Vref; and a second D-mode MOS for supplying Iin based on Vdiv. The E-mode MOS is the same as the first D-mode MOS in conductivity type and impurity concentration of a channel, and is different from the first D-mode MOS in Fermi level of a gate electrode. The voltage dividing circuit supplies Vdiv higher than a threshold voltage of the second D-mode MOS and lower than a cross point (X) to a gate terminal of the second D-mode MOS.
