      Some problems to consider from the book - not for grading

Diodes:
	page 224, #3.38 and #3.39; also estimate the saturation 
	     current of the diode and find the Q point algebraicly
	     using it.

BJT bias and small signal parameters:
       page 528, #D5.89; also assume beta=100 and VA=200, find
	    the small signal pi-equivalant circuit and the 
	    corresponding Y matrix. 

MOS biasing and small signal parameters:
      page 362, #D4.36 and #D4.37
      page 361, #4,23; also give the pi-equivalent circuit and
	   the corresponding Y matrix for the original Q point.

Current mirrors:
	MOS
      page 668: #6.21; also replace Iref by a diode connected
	   PMOS transistor complementary to the NMOS but with
	   suitable W/L to give the desired Iref.

        BJT
      page 669: #6.32 and #D6.33
