sawtooth generator - RF Cafe Forums
Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.
Below are all of the forum threads, including all the responses to the original posts.

I was wondering if there was anyone who knew how to make a very high frequency sawtooth generator, or possibly very clean high frequecny pulses to discharge a cap for sawtooth generation. everything i have tried is unaccecptable at the frequencies i am interested in.

Um, how are we going to help you if you are having trouble at "the frequencies i am interested in" if you don't tell us what those frequencies are?

in the megahertz range

That's still not very specific. What's so hard about naming your frequency range? 1-10 MHz? 100-500 MHz? It makes a difference.
Here's a Maxim MAX038 waveform generator circuit for up to 20 MHz.
This circuit probably goes beyond 50 MHz

The best thing to do probably is call some of the IC vendors and talk to an applications engineer. They'll know right away if they have a solution, and the advice is free.
