I'm trying to dabble in analog circuit design, but I honestly am a complete newcomer in this area as my strengths are in CS. Sorry if this question sounds stupid, but can anyone help me with designing a voltage follower that can deliver large amounts of current to an external circuit (a purely resistive circuit). I've come up with a simple solution that doesn't quite work as the feedback load regulation is really bad (the voltage doesn't transfer over well).
Since I require a large amount of current, I can't just design an op amp voltage follower since I don't want to opt for the more expensive op amps that can provide upto 5A (if they even exist).
My attempt: . The voltage over the resistor is close to 3V instead of the 8V that I want. The voltage over the load should stay the same regardless of the load value.
Any help in this matter would be greatly appreciated! Thank you so much!
