Current differencing buffered amplifier

A current differencing buffered amplifier is like an amplifier that takes a small electrical signal, called an input signal, and makes it bigger, called an output signal. It works by taking the input signal and splitting it into two different signals. One of the signals is reversed in direction. These two signals are then fed into two specially designed transistors (the buffer) which have a similar internal structure, making them react in a similar way. The transistors then combine the two signals and produce a stronger signal which is then fed through an output stage. This output signal is bigger and stronger than the original input signal.
