ABSTRACT:
Disclosed is a CMOS current mirror circuit including a first MOS transistor and a second MOS transistor constituting a current mirror, in which a drain of the first MOS transistor and a gate of the second MOS transistor are connected in common, a source of the first MOS transistor is directly grounded, and a gate of the first MOS transistor is connected to the drain of the first MOS transistor through a third MOS transistor which has a source connected to the drain of the first MOS transistor, a drain connected to the gate of the first MOS transistor, and a gate being biased. The source of the second MOS transistor is directly grounded. Current is input to the drain of the third MOS transistor. The drain current of the second MOS transistor is mirrored by cascode current mirror circuits. An output current is output from the source of a MOS transistor for conversion to a voltage by a circuit that receives the current which outputs a reference voltage.
