Question

The R/2R ladder network shown on the right can be most easily (and therefore most accurately) analyzed using the superposition method, since the circuit is linear. That is, you can calculate the output voltage due to each bit independently (with all the other voltage sources turned off), and sum the voltages from each bit to obtain the final result. Here each voltage source (V0~V3) represents the voltage input from each digital bit and shall have values of either VDD (the supply voltage) or zero. You can write it as Vi= di VDD, where diis the i

Explanation / Answer

please rate this applying super position V analog due to V3 = (250K/350K )*V3 consider others =0 V analog due to V2 = (200K/300K )*V2 consider others =0 V analog due to V1 = (150K/250K )*V1 consider others =0 V analog due to V0 = (100K/200K )*V0 consider others =0 now add all these V analog = F(d0, d1, d2, d3) =(250K/350K )*V3 *d3 + (200K/300K )*V2*d2 + (150K/250K )*V1*d1 + (100K/200K )*V0*d0 Answer
