Table 1 Supply voltage requirements for practical applications

From: Ultra low-voltage CMOS current mirrors

Current mirror	Minimum supply voltage	Dynamic range
Simple	\(V_{th}+2V_{sat} +V_{DR}\)	V _DR	Unidirectional
Cascode	\(V_{th}+2V_{sat} + V_{DR}\)	V _DR	Unidirectional
Wilson	\(V_{th}+2V_{sat} + V_{DR}\)	V _DR	Unidirectional
MITE	\(V_{th}+2V_{sat} + V_{DR}\)	V _DR	Unidirectional
ULV	V _th	\(V_{th}-2V_{sat}\)	Bidirectional
