Chapter 4 Problems: 10, 11, 13, 21, and 24 10. Assume a JFET has the transconductance curve shown in Figure 4–76 . (a) What is I DSS ? = 6.4mA (b) What is V GS(off) ? = 5V (c) What is the transconductance at a drain current of 2.0 mA? = 910µA 11 . Assume the JFET with the transconductance curve shown in Figure 4–76 is connected in the circuit shown in Figure 4–77 . (a) What is V S ? = 6.4V (b) What is I D ? = 6.4mA (c) What is V DS ? = -12.5V 13 . For each circuit in Figure 4–78 , determine V DS and V GS . a) V GS = - 1V ; V DS = 10V

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
