This page talks about how to design a simple BJT common emitter amplifier. Below are the full derivations for component values because I CBA to work this out every time some fellow student asks me to explain this after they fail the EE exam ;) Thanks to the professor who can't explain this clearly enough on the lecture for the n-th year.
Task
Below is an NPN common emitter amplifier. Design the elements so that
- Collector current Ic = 1mA
- Collector-emitter voltage Uce = 6V
- Voltage gain for the AC component Ku = ΔU2/ΔU1 = 23
- Current for resistors R1 and R2 is much larger than the base current
- Supply voltage Ecc = 12V
