CHP 7 MOSFET Amplifier: 7.1 Signal Amplification

  • Signal amplification (analog):










  • Depending on internal structure, an amplifier can amplify input current, voltage or both
  • When V x I product of output exceeds input's, power gain results
  • A device must provide power gain to be called an amplifier 
  • Noise tolerance through amplification:
















  • Another amplifier application: buffering
