![]() The specifications are input impedance, efficiency, bandwidth, gain, slew rate, linearity, stability, etc. We need to consider the following specifications before choosing the transistor amplifier. Note: Most of amplification circuits uses CE configuration because it has high gain and high input impedance. Common Emitter configuration (CE): in this configuration emitter is connected to ground and we will have input impedance will be high, output impedance will be medium and gain will be high.Common Collector configuration (CC): in this configuration collector is connected to ground, we have low output impedance for high input impedance and gain for this configuration is very good when compared to CB configuration.Gain for this configuration will be very low. ![]()
