Hello again, I have a opamp servo that has a max output voltage of about 40v and I need to output more voltage than it's rated for. I need a linear voltage swing of +25v (maybe more) to -150v.
I'm starting to reach the point where my limited understanding of transistors is becoming a bottleneck.
From my understanding, mosfets are terrible voltage amplifiers and will need some sort of feedback to linearize them. Also from what I understand I would need a P type mosfet and they don't amplify positive voltages correct?
Any advice on how I would go about doing this?
To sum up I need to have my opamp servo which currently swings +/- 40v and amplify its output with a gain of 5 so it can become +/-150v which will be used as a voltage reference for a vacuum tube's grid bias.
