30/05/2016 · I tried to design R2R DAC structure at in my circuit. In my thought R2R DAC is more area effective DAC than conventional R-String DAC. However, R2R DAC has some disadvantages. 1. VCR Issue - In CMOS process, poly-silicon resistor or diffusion resistor has voltage coefficient. that is to say, resistor value is dependent for voltage across resistor.

A digital to analog converter with an R-2R ladder network as shown in figure 2 eliminates these complications at the expense of an additional resistor for each bit. Figure 2: DAC Employing R-2R Ladder Network. The operation of R-2R ladder DAC is easily explained considering the weights of the different bits one at a time.

R-2R Ladder One of the most common DAC building-block structures is the R-2R resistor ladder network shown in Figure 3.15. It uses resistors of only two different values, and their ratio is 2:1. An N-bit DAC requires 2N resistors, and they are quite easily trimmed. There are also relatively few resistors to trim. Figure 6.13: 4-Bit R-2R Ladder ...

Going through the mathematical proof for the operation of this converter can be a pain for some of us, and I am only intending to keep things simple. Now, in order to use this Resistor Network (also called R/2R Ladder) for real applications, you will have to build a very simple voltage buffer circuit, which will be explained in the next section.

weights of the C, B, and A bits to obtain 4 V + 2V + 1V=7V. Problem 3 A 5-bit D/A converter produces V OUT = 0.2 V for a digital input of 0001. Find the value of Vout for an input of 11111. Solution Obviously, 0.2 V is the weight of the LSB. Thus, the weights of the other bits must be 0.4 V, 0.8 V, 1.6 V, and 3.2 V respectively. For a
