The schematic above is a very good voltage regulator, excepting the high power dissipation for Q1 (also I'd use an NPN instead of a PNP). Can I replace Q1 and Q2 with a high current n-mosfet and ...
In an attempt to have a square wave with a voltage-controlled amplitude, I've made this little circuit: Unfortunately, when negating, it has a slight offset from -Vin. I assume this is because ...
So I've seen alot of explanations on two stage voltage amplifiers and how how their gains can be multiplied together. My question is when you are using a two stage common emitter amplifier for current ...
