What are the differences between a (pnp) and a (npn) Bipolar Junction Transistor?
These are the four modes for the bipolar junction transistors (PNP type). FOR THE ACTIVE CASE: I am having trouble understanding why the minority carriers (electrons) increase in the emitter region as you approach the depletion region. Similarly, why is there so much minority carriers in the base (and why does it decrease as it approaches the base collector junction). Also why are the minority carriers (n) in the collector region initially very low, the increases? Can you explain how...
What are important similarities and differences between the manic phase of bipolar disorder and schizophrenia?
A. As an electronic device, what is the function or purpose of a bipolar junction transistor when it is utilized in an analog circuit? B. Make a sketch of a typical volume element of a silicon pnp transistor connected in active larger than the base current. In your sketch, show the path of carriers (both holes and electrons) as they proceed from the emitter to the collector. Identify the paths of all 3 types of base current and explain what...
Sketch structure of depletion-enhancement MOS Filed Effect Transistor (DE-MOSFET). Explain essence of principle of operation of E-MOSFET connected in common-source configuration. Sketch and explain shapes of corresponding common-source transfer curves and common-source output curves (drain IV characteristics). Explain why input IV characteristics are not used in the case of FET.
Q2. Answer each of the following: (a) When a bipolar junction transistor (BJT) is used as an electronic switch, what operating regions does the BJT alternate between? For each operating region identified, what way are the junctions of the BJT biased? (b) Explain what each of the operating regions, identified in part (i) of this question, mean and clearly state the important conditions that are necessary to ensure that the BJT is operating in each of these regions. Include a...
2. True or false: a. Schottky barrier diodes typically have lower leakage current than p-n junction diodes b. The semiconductor drift current is proportional to the magnitude of the electric field. c. The ideal subthreshold slope for a MOSFET increases with increasing temperature d. For a MOSFET the density of inversion-layer charge is QinrsonCx VGS VFB e. For a MOSFET the following equation is correct: on inversion -Raccumulation VGS-VFB f. For a BJT the following equation is correct: -- 1-a...
1) 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. 2) Describe...
For this concept sketch I'd like you to sketch, label, and describe the Greenhouse Effect. You must include the relationships between incoming (short wavelength) solar energy, infrared (long wavelength) energy radiated by the earth, and greenhouse gasses in the atmosphere. Your sketch and description should include the different paths for incoming solar energy, and at least 3 different greenhouse gasses. Please help asap
