Binary weight current DAC mismatch

[bageduke]

I am doing current DAC design. Could someone give me some idea about how to decide the W and L sizes of current source(MOS transistor)? Such like my foundry supply me with mismatch percentage of smallest transistor size and I want to design 10-bits DAC.

Thanks a lot
