I have a related circuit I am working on and was wanting some pointers. Firstly I'd like to have a circuit that puts out a good clean square wave so as to minimize losses. I have good powerful FDH44N50 Mosfets to drive most any load. It would be nice to have a min and max set point so then a variable resistor can swing between those two set points. Having it go from near 0% duty cycle up to a set point would work great. I have tried using 7414 Hex Schmitt Trigger to do this and it was ok but I'm looking to improve this. I have one circuit I've found that may just do it but would love some feedback from anyone who can offer some direction. This is a personal project and I have played with a number of flip flop configurations along with buffers, drivers, and waveform correction while still not getting the response I'm looking for. Ideally I'd like to operate in the range of 40-100kHz
