A current mirror topology is proposed that provides
very high precision, design insensitive up and down
mirrored current, operation over a wide power supply
range, straightforward design, and the possibility of conveniently
obtaining a wide range of current divisions. This
topology is appropriate for those applications in which precise
current handling is necessary such as high accuracy A/D
and D/A converters and reference cells
