Consider the 2-bit multiplexer (MUX) shown in the figure. For OUTPUT to be the XOR of C and D, the values for A0, A1, A2, and A3 are ____________.

A0 = 0, A1 = 0, A2 = 1, A3 = 1
A0 = 1, A1 = 0, A2 = 1, A3 = 0
A0 = 0, A1 = 1, A2 = 1, A3 = 0
A0 = 1, A1 = 1, A2 = 0, A3 = 0

Correct answer: A0 = 0, A1 = 1, A2 = 1, A3 = 0

Solution

The correct option sets the multiplexer inputs such that the output reflects the XOR operation between inputs C and D, which requires specific combinations of the select lines to enable the correct input paths for the desired output.

Consider a long rectangular bar of direct bandgap p-type semiconductor. The equilibrium hole density is 10¹⁷ cm⁻³ and the intrinsic carrier concentration is 10¹⁰ cm⁻³. Electron and hole diffusion lengths are 2 μm and 1 μm, respectively. The left side of the bar (x = 0) is uniformly illuminated with a laser having photon energy greater than the bandgap of the semiconductor.
