Extracted text: 2. a) With reference to the output characteristics explain what is meant by the terms cutoff, active and saturation of a bipolar junction transistor. Indicate these regions on a sketch of the transistor output characteristic. b) What is the equation of the load line shown in Figure 2b? Rc + 12 volts Rg +V8 Figure 2b Question 2 continues on next page


Extracted text: c) A silicon bipolar junction transistor is to be used in an inverter shown in Figure 2c. For this particular group of BJTS B varies from 100 to 200. Design appropriate values for resistors Rc and RB so that the inverter passes a current of Io > 150 mA. State any assumptions you make. 10 V Rd + 10 V VIN OV Figure 2c d) Briefly describe how an n-channel enhancement MOSFET works, and the essential condition for it to operate. e) Sketch the output characteristics of a MOSFET. What are the modes of operation?
