please guide me to design currentcell for two LSB and six MSB?

what is delay element in digital?

the answer is inverter.

Generally the delay in CMOS technology is the capacitance...becasue we need time to charge and discharge...when added some extra circuit(even as small as inverter) it will increase your delay.....

MAybe u mean that inverter is used to build buffer so it's a delay element....

Well for 14bit DAC u can build it using R2R network, it's smaller but be careful with the op-amp, the non-lineraity and offset can disturb your DAC output, and resistor matching is very important
