Trying to build a square wave generator (high frequency) and H-bridge
I was wondering if someone could help me out at building a high frequency variable square wave generator.
Specs: 100kHz - 1Mhz (better if I can get up to 3Mhz),
5 to 20V, square wave.
Right now I have a LM555 timer. I have read online that I can get it to run at maximum 1Mhz. I don't know what I'm doing wrong, but I can't get it to output at higher frequencies.
Also, does anyone know of a good H-bridge circuit schematic that could output 24V pk-pk at 3A. I will be using the signal from the square wave generator to feed to the H-bridge, therefore, is there a H-bridge design that can handle high frequencies? Or, is there another driver circuit that I could use instead of a H-bridge that could do the same job or better?
