OUTPUT AMPLIFIER WITH NON-LINEAR NEGATIVE FEED BACK

摘要

The output amplifier has a non-linear negative feedbackand is used to protect the amplifier against overload. It can be used for car radios and can be designed as an integrated circuit. The amplification circuit consists of two halves in a bridge network. The two halves are high output operational amplifiers (1,2) supplied in anti-phase from a signal scurce(7).
