APPENDIX F
Transistor and Amplier Formulas
The following formulas are meant as a reminder of the fundamentals given in most standard electronics textbooks. Notation for the formulas have the traditional meanings. Depletion capacitances are all given with a negative sign in the denominator as in C D C0 / 1 V/ . Consequently, when the junction is reverse biased, the minus sign turns into a positive sign. Figure F.1 presents the basic FET features and symbols. Bipolar Transistor Parameters (BJT)
