Question

In integrated circuits, npn construction is preferred to pnp construction because

• A. npn construction is cheaper
• B. to reduce diffusion constant, n-type collector is preferred
• C. npn construction permits higher packing of elements
• D. p-type base is preferred

Answer 1

The correct option is B to reduce diffusion constant, n-type collector is preferred

In integrated circuits, npn construction is preferred to pnp construction because to reduce diffusion constant, n-type collector is preferred.
