hi all
I am doing 12 bits DAC with classical segmented current steering structure. Totally I have 40 bipolar cascode current cells. Could anyone suggest me how to design the bias circuitry to bias these current sources? How should I divide them into several groups and what kind of current mirror structure is better? Thx in advance
