Hi, I need to design a 8-bit DAC. I also need to design the Op-amp that is used in DAC. I studied in Analog Integrated Circuits Design (Johns,Martin) book that the op-amp could drive either resistor or capacitor load. If the load is resistor, buffer stage should be included in the discrete op-amp design. So i am thinking, Since the op-amp in R-2R DAC has the resistors in the feedback i need include buffer stage in the design.
I want to confirm whether my understanding is correct. Kindly provide any information on how to design an opamp that includes buffer stage in its design.Thanks
