The Bipolar Junction Transistor (BJT) Differential Amplifier (084c)
In this video I will present the bipolar junction transistor (BJT) differential amplifier. It is an AMAZINGLY SIMPLE circuit. I will explain about its linearity, gain and input impedance. I even did a bench experiment which had a gain of over 40 dB! ======================================= LINKS -------------------------------------- The Current Source Videos Video #1: Classic BJT Current Sources: • Bipolar Junction Transistors (BJT) Current...
