Concider the circuit below known as "Inverted R-2R Ladder" DAC.

Consider the circuit below known as V. REF + I 2R 2. 2R MSB R R 2R "Inverted R 2R Ladder "DAC. R 2RS = R Cx 2R e) Do parasitic capacitances such as C & C delay" transients which can slow down the LSB C = parasitic capacitances. y www. 2R Ideal is a constant independent of the a) Show that the current I drawn from V, input digital word (b bb). REF b) What is the switch current and V. if the MSB is 1 and all other bits are 0 ? c) Repeat b), assuming that the next MSB is 1 and all other bits are 0. d) Calculate V for the LSB in the 4-bit DAC O with all other bits zero. have an influence on "propagation- system ?
