<For Charge Pump items>

Ia=Charge pump sink current at Vcp=Vp-

∆V,

Ib=Charge pump sink current at Vcp=Vp/2,

Ic=Charge pump sink current at Vcp=

∆V

Id=Charge pump source current at Vcp=Vp-

∆V, Ie=Charge pump source current at Vcp=Vp/2,

If=Charge pump source current at Vcp=

∆V

∆V=Voltage offset from positive(for sink current) and negative(for source current) points from which the charge pump currents

become flat.

* Output Current Sink vs. Source Mismatch = [| Ib|-|Ie|] / [0.5 * {| Ib|+|Ie|}] * 100 (%)

** Output Current Magnitude Variation vs. Temperature =

[| Ib @any temp.| - |Ib @ 25

οC|] / | Ib @ 25οC| * 100 (%) and [|Ie @any temp.| - |Ie @ 25οC|] / |Ie @ 25οC| * 100 (%)

*** Output Current Magnitude Variation vs. Voltage =

[0.5 * {|Ia|-|Ic|}] / [0.5 * {|Ia|+|Ic|}] * 100 (%) and [0.5 * {|Id|-|If|}] / [0.5 * {|Id|+|If|}] * 100 (%)
