Problem statement: design a small-signal voltage amplifier using bjt's that meets the following specifications: 1) voltage gain of 50 or more 2) minimum input resistance of 15 kω 3) output resistance less than 100 ω 4) maximum unclipped output of 2v peak-to-peak 5) power supply voltage of 9 v 6) lower current drain from supply voltage

hint: you may use a multi-stage small-signal amplifier to achieve desirable input resistance, voltage gain, output resisntace, etc. a common-emitter amplifier with an emitter resistance re, but without an emitter by-pass capacitor ce is good for high input resistance, common-emitter amplifier using an emitter bypass capacitor is good for high voltage gain, and the use of an emitter follower results in a low output resistance.
