- A voltage VA 23.03(kT/q) is being applied to a step junction diode with n and p side dopings of NA = 10¹7/cm³ and ND = 10¹6/cm³, respectively. N₁ = 10¹º/cm³. a) Make a dimensioned log (p and n) versus x sketch of both the majority and minority carrier concentrations in the quasineutral regions of the device. b) Identify points 10 and 20 diffusion lengths from the depletion region edges on your sketch.arrow_forward2 images to lookarrow_forwardThe logic diagram contains interactive switches and an LED. This allows us to immediately simulate the circuit and view the response. Run the simulation and click on the switches to operate them. View the response for different switch combinations. As well as this interactive execution, we can use the Logic Converter instrument to generate a truth table and Boolean expression. This will help us simplify the circuit. Select the Logic Converter from the instruments toolbar. (Do i have to put the logic converter to do step 1?) Why can't I get power in the circuit from the image provided? Can you tell me which gates are labeled into which section?arrow_forward
