11: JFET Small Signal Amplfiers

( \newcommand{\kernel}{\mathrm{null}\,}\)

Learning Objectives

After completing this chapter, you should be able to:

  • Determine the voltage gain, input impedance and output impedance of basic JFET amplifiers.
  • Draw and explain a basic AC model of a JFET.
  • Compare and analyze JFET voltage amplifiers and voltage followers.
  • Discuss the advantages and disadvantages of JFET circuits with those of comparable BJT circuits.
  • Analyze small signal combination BJT/JFET amplifier circuits.
  • Discuss applications that make use of the JFET's ohmic region.
