EE3114 Electronics I Homework #6 BJT DC Biasing Assignment Due 1 Week 1) Textbook Problem 5.1 2) Textbook Problem 5.2 3) Textbook Problem 5.5 4) Textbook Problem 5.10, since V BE = 0.615v, we are looking for a more accurate value for I C . For this case, use the more general equation T BE V v S C e I i = 5) Textbook Problem 5.17, use the approximate value for V B E = 0.7v. 6) Textbook Problem 5.53, use the approximate value for V B E = 0.7v. 7) For the following BJT circuit having DC bias as shown. Use V B E
