Problem Statement: Design a small-signal voltage amplifier that meets the following specifications: 1) Voltage gain of 50 or more 2) Minimum input resistance of 15 k 3) Output resistance less than 100 4) Maximum unclipped output of 2V peak-to-peak 5) Power supply voltage of 9 V and lower current drain from supply voltage 6) A two-stage small-signal amplifier is more cost effective than a three-stage amplifier design 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 by- pass capacitor is good for high voltage gain, and the use of an emitter follower results in a low output resistance.

help  with some explanation

Problem Statement: Design a small-signal voltage amplifier that meets the following
specifications:
1) Voltage gain of 50 or more
2) Minimum input resistance of 15 k
3) Output resistance less than 100
4) Maximum unclipped output of 2V peak-to-peak
5) Power supply voltage of 9 V and lower current drain from supply voltage
6) A two-stage small-signal amplifier is more cost effective than a three-stage amplifier design
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 by-
pass capacitor is good for high voltage gain, and the use of an emitter follower results in a low
output resistance.
