Glitch free High speed DAC topologies

[MHML]

Hi dears,
In my design, DAC's output must be glitch free analog outs but i don't know witch topologies of DAC can be Glitch free and remained High speed?!
Glitch freeing methods can down speed of DAC?
Please send any your suggestions or new methods.

Regards.

hai larijani,

you can try to use current-steering DAC with unary-weighted selection... it's a high speed topology because it can drive a resistive load without any buffer needed..
