This is a continuation of last time, where we learned how a simple differential amplifier (diff amp) works. We're going to take that design and add a clever thing called a current source in the 'tail' of the circuit, and see how that makes the circuit voltage controllable!


This is a more advanced, and much improved VCA compared to my 1 Transistor VCA. We've come a long way!
