Design a common emitter amplifier with a target gain of 100. If V_CC is 15V, and we choose a collector resistor drop of 7V, what are the values for R_C and bias resistors?
💡 Hint: Start by calculating the necessary I_C from the desired voltage gain.
Given a transistor with β = 120 and I_C = 2 mA, what is the required I_B? Additionally, determine the voltage drop across a 4.7KΩ collector resistor.
💡 Hint: Use Ohm's law and the collector current to find resistance values you're interested in.
