Summary: 
Two high output-resistance CMOS current mirrors suitable for a low-voltage operation and achieving a high output-swing are presented. They incorporate a modified regulated-cascode, which employs a current-mode amplifier. The main architecture concepts and their detailed schematic examples are discussed. SPICE simulation comparison is shown and the properties of each architecture are pointed out.
