Title: Low-voltage current mirror circuit

Abstract: The low voltage current mirror circuit of the present invention includingmultiple circuit elements each forming a current mirror, and concatenatingthe multiple circuit elements to form a cascode current mirror circuit,comprises voltage dropping means for mutually connectinginter-control-electrode nodes of each of the multiple circuit elements, tocause the predetermined voltage drop between the inter-control-electrodenodes. According to such a simplified constitution, it is realized tolower the input voltage and output voltage of the current mirror circuit.
