  1. Common-Collector Amplifier Section 13.1-13.4

  2. A note about Human Ear • Human can hear between 12 Hz and 20 KHz. • The range begins to shrink at the age of 8 with high frequency fading.

  3. Vs,pp=100 mV, Freq=1 KHz

  4. Vs,pp=100 mV, Freq=1 KHz mV

  5. Vs,pp=100 mV Slight mismatch Bias current of Q2=13 mA 13 mA x 8 Ohms=104 mV

  6. Apply a small Signal (Vpp=30 mV)

  7. Increase the Input Frequency 3dB BW=1.9 MHz

  8. Typical Audio Signal Limited output Swing

  9. Audio Plug

  10. Power Dissipation of Q1 Assumption: The instantaneous power dissipated by Q1:ICVCE Average Power

  11. Power Dissipation of the Current Source

  12. Efficiency

  13. Efficiency of Emitter Follower • Pdiss of Q1: • Pdiss of I1: • Total power wasted in Q1 and I1: • Output power:

  14. Improved Push-Pull Stage

  15. DC Bias

  16. Voltage Gain

  17. Output Impedance
