摘要：A balanced low impedance differential input line preamplifier comprising adifferential amplifier and a pair of high gain common base input stages. The input signal isdirectly applied to the emitters of the common base input stages and the collectors ofthe common base input stages are each connected to one input of the differentialamplifier. Capacitors are used to DC decouple the common base input stages to thedifferential amplifier.
