Low-voltage floating-gate current mirrors

In this paper we propose a novel design of low-voltage current mirrors using floating gates. Floating gate UV-light programmable MOS transistors (FGUVMOS) are used to design current mirrors in low-voltage/low-power analog applications. The capacitive divider inputs to the floating gates can he utilized to reduce current mismatch due to Early effect.
