8.8 A PMOS current mirror consists of three PMOS transistors, one diode connected and two used as current outputs. All transistors have and L = 1.0 µm but three different widths, namely, 10 µm, 20 µm, and 40 µm. When the diode-connected transistor is supplied from a 100-µA source, how many different output currents are available? Repeat with two of the transistors, diodes connected and the third used to provide current output. For each possible input-diode combination, give the values of the output currents and of the VSG that results.
