Dc Current Amplifier Circuit. December 3 2010 rend. This process is termed as current amplification of an input signal.
Beside that this circuit can amplify a very low ac frequencies since no capacitive reactance. Signal load and the amplifier bias are separate. Whenever we applied a positive half cycle at the input of the primary transistor q1.
This amplifier amplifies the ac signal by low frequency.
A current amplifier is somewhat similar to a voltage buffer but the difference is that an ideal voltage buffer will try to deliver whatever current required by the load while keeping the input and output voltages same where a current amplifier supplies the succeeding stage with a current that is a fixed multiple of the input current. December 3 2010 rend. No dc current flows through the load or through the signal source. Since there is no coupling capacitor to block dc this circuit can perform as dc amplifier as well as ac amplifier.
