It used to be a rite of passage to be able to do the math necessary to design various bipolar transistor amplifier configurations. This doesn’t come up as often as it used to, but it is still a good ...
The 2N2222 and BC549 transistors are two old components that are still universally used in the vast majority of electrical circuits today. Their applications include amplifiers, filters, impedance ...
This way, 10 simulations will be run, each with a different resistance value between 1 KOhm and 10 KOhm. As usual, the different behaviors will be studied with the LTspice and ngSpice software.
