1.41 Consider an N-bit DAC whose output varies from 0 to VFS (where the subscript FS denotes “full-scale”). (a)Show that a change in the least significant bit (LSB) induces a change of VFS/(2N − 1) in the output. This is the resolution of the converter. (b)Convince yourself that the DAC can produce any desired output voltage between 0 and VFS with at most VFS/2(2N − 1) error (i.e., one-half the resolution). This is called the quantization error of the converter. (c)For VFS = 5 V, how many bits are required to obtain a resolution of 2 mV or better? What is the actual resolution obtained? What is the resulting quantization error?

1.6 Figure P1.6(a) shows a two-resistor voltage divider. Its function is to generate a voltage VO (smaller than the power-supply voltage VDD) at its output node X. The circuit looking back at node X is equivalent to that shown in Fig. P1.6(b). Observe that this is the Thévenin equivalent of the voltage-divider circuit. Find expressions for VO and RO.

D 1.8 You are given three resistors, each of 10 kΩ, and a 9-V battery whose negative terminal is connected to ground. With a voltage divider using some or all of your resistors, how many positive-voltage sources of magnitude less than 9 V can you design? List them in order, smallest first. What is the output resistance (i.e., the Thévenin resistance) of each?
