METHOD OF INCREASING OUTPUT CURRENT CAPABILITY OF NEGATIVE FEEDBACK AMPLIFIERS WITH OUTPUT CURRENT LIMITING AND FREEDOM FROM THERMAL RUNAWAY

摘要

A high output current negative feedback power amplifier amplifies an input signal by use of a monolithic operated amplifier with a current limiting resistor in its output path. The output current of the amplifier is automatically increased when the voltage drop across the current limiting resistor increases beyond a predetermined point and global current limiting automatically occurs when the output current of the monolithic amplifier exceeds a predetermined point.
