## Describe And Explain Drift Current And Diffusion Current In A PN Junction In Thermal

Describe and explain drift current and diffusion current in a PN junction in thermal equilibrium. What causes each? In which directions are the electrons, holes, electron current, and hole current flowing for each effect? What is the net current? Assume the built-in E-Field points to the left. Use a diagram. Then describe what changes when an electric field is applied, positive side on the N terminal. Describe what happens when the magnitude of that field is reversed. Describe how the hot point probe uses diffusion to determine the type of semiconductor material.

## 1: A Switch-tail Counter (also Called Twisted Ring Counter Johnson Counter) Uses The Complement

1: A switch-tail counter (also called twisted ring counter Johnson counter) uses the complement of the serial output of a right shift register as its serial input. (a) Starting from an initial state of 000, list the sequence of states after each shift until the register returns to 000. (b) Beginning in state 00…0, how many states are there in the count sequence of an n-bit switch-tail counter? (c) Design a decoder to be driven by the counter that produces a one-hot code output for each of the states. Make use of the don’t-care states in your design. 2: The outputs of registers RO, R, R2, and R3 are connected through 4-to-1 multiplexers to the inputs of a fifth register, R4. Each register is 8 bits long. The required transfers, as dictated by four control variables, are Co: R4 – RO Ci: R4 <- R1 C2: R4 <- R2 C3: R4 <- R3 The control variables are mutually exclusive (i.e., only one variable can be equal to 1 at any time) while the other three are equal to 0. Also, no transfer into R4 is to occur for all control variables equal to 0. (a) Using registers and multiplexer, drawa detailed logic diagram of the hardware that implements single bit of these register transfers. (b) Draw a logic diagram of the simple ogic that maps the control variables as inputs to three outputs: the two select variables for the multiplexer and the load signal for the register R4 a a

## Explain The Concept Of Electron And Hole Mobility. How Is Mobility Affected By Temperature?

Explain the concept of electron and hole mobility. How is mobility affected by temperature? Impurity concentration? How and why is hole mobility different than electron mobility? Mobility is related to conductivity. Why does conductivity increase with increased doping even though mobility decreases? Describe why the intrinsic carrier concentration changes with temperature. This would include from very cold temperatures to 600K temperatures. Why does an extrinsic semiconductor become intrinsic above ~ 500K? Draw a graph and label it carrier concentration vs. temperature

## 4: Develop A State Machine Diagram For A Traffic Light Controller That Works As

4: Develop a state machine diagram for a traffic light controller that works as follows: A timing signal T is the input to the controller. T defines the yellow light interval as well as the changes of the red and green lights. The outputs to the signals are defined by the following GN Green Light, North/South Signal YN Yellow Light, North/South Signal RN Red Light, North/South Signal GE Green Light, East/West Signal YE Yellow Light, East/West Signal RE Red Light, East/West Signal While T 0, the green light is on for one signal and the red light for the other. With T 1, the yellow light is on for the signal that was previously green, and the signal that was previously red remains red. When T becomes 0, the signal that was previously yellow becomes red, and the signal that was previously red becomes green. This pattern of alternating changes in color continues. Assume that the controller is synchronous with a clock that changes much more frequently than input T 5: Develop a C program that demonstrates the behavior of the circuit in question 4. The code should be submitted as a CPP file or a link to the online IDE
