Compare CE,CC and CB configuration of BJT
1 Answer
Characteristic Common base (CB) Common emitter,(CE) Common collector,(CC)
Input Dynamic Resistance Very Low(less than 100 ohm) Low(less than 1K) Very High(750K)
Output Dynamic Resistance Very High High Low
Current Gain Less than 1 High Very High
Voltage gain Greater than CC but less than CE Highest Lowest(less than 1)
Power gain Medium Highest Medium
Leakage current Very small Very large Very large
Relationship between I/p and o/p In phase Out of phase(180ยบ) In phase
Application For High freq. applications For Audio freq. Applications For impedance Matching Applications
