You found the input and output resistances of your
common-emitter amplifier. Explain, in your own words, why these
values are of practical interest when designing
circuits. What happens to your gain, generally, when you attach a
load resistance? If you wanted to preserve at least 90% of your
measured no-load gain when you hook up a load, how to calculate the
value of the minimum load resistance value that would be
acceptable.

You are required to design a 2-stage voltage amplifier (find
values for RE, RC1, RC2) to meet the following criteria: an input
resistance of 400 kΩ and an overall voltage gain equal to or
greater than 250, with a resistor output load, RL. Use a
common-emitter with emitter degradation (RE) stage for the input,
followed by a commonemitter amplifier with bias current equal to
0.5 mA. (VCC = 20 V, βo = 200 and the DC levels of the first...
