Hello,
I am a software engineer with basic electronic skills gone mad starting a project that appeared to be straight forward. Wrong!! Frustrating! I have however turned my frustration into a goal, that being to learn something by taking the following described project to completion. If this project is appropriate to this forum let me know. I look forward working with you all.
My project is to replace a heavily biased, heat generating, hybrid amplifier with a 0 biased amplifier. The requirements for the replacement amplifier are: operating frequency 300 MHz max; input level 0-5v; output supply voltage 100vdc; 0 bias push-pull output stage; output drive level 10-90vdc; tunable gain 20-40.
My concept is to drive a push-pull pair with an op amp incorporating feedback to keep one of the output pair in conduction eliminating crossover distortion.
Is this concept viable?
