5. IDO vs VDO = Charge Pump Output Current magnitude variation vs Voltage =
[1/2 •{|I1| - |I3|}]/[1/2 • {|I1| + |I3|}] • 100% and [1/2 • |I4| - |I6|]/[1/2 • {|I4| + |I6|}] • 100%.
6. IDO-SINK vs IDO-SOURCE = Charge Pump Output Current Sink vs Source Mismatch = [|I2| - |I5|]/[1/2 • {|I2| + |I5|}] • 100%.
7. IDO vs TA = Charge Pump Output Current magnitude variation vs Temperature =
[|I2 at temp| - |I2 at 25oC|]/|I2 at 25oC| • 100% and [|I5 at temp| - |I5 at 25oC|]/|I5 at 25oC| • 100%.
