Response to the following question:
A PMOS current mirror consists of three PMOS transistors, one diode connected and two used as current outputs. All transistors have / Vt /= 0.6 V, kΩ p = 100 μA/V2, 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 diode 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.
