This paper describes design principles and methods of the preamplifiers of acoustic emission instrumentations. This kind of preamplifier is a low-noise
high sensitivity and wide band amplifier. The paper also points out the selection methods of circuit parameters and the test of the characteristic indexes of the preamplifier.
