Common-Collector Configuration

• Collector terminal between input and output side
• Input current and input voltage is IB and VCB
• Output current and output voltage is IE and VCE

Common-Collector Configuration

• Voltage gain of common collector configuration is nearly equal to one
• Current gain of common-collector configuration is β+
• Common-collector configuration have high input resistance and low output resistance
• Common-collector configuration is used for impedance matching for maximum power transfer ( connecting a high resistance source to a low resistance load)

Operation Limit

• There are limits to the operation of a transistor to

ensure minimum distortion in the output signal

• These limits include
  • Maximum collector current (ICmax)
  • Maximum collector-emitter voltage ( VCEO)
  • Minimum collector to-emitter voltage (VCEsat)
  • Maximum power dissipation level (PCmax)

Operation Limit

Operation Limit

• The operating point should be between these limits
• Common-base
• Common-collector
• Common-emitter
