Simple TTL signal generator/counter with sum

<< < (2/2)

Well. One can, of course, harness an entire buffer to output the needed power. Another option would be to use small low threshold N and P fets connected fae-to-face. Of course one needs some sort of current limitation as these WILL conduct at same time, being a very short time that could be two tiny inductors.

I made a largeish FET gate driver circuit that was capable of outputting 15 V/pp into a 0.47uF capacitor @ 10KHz. The test capacitor fried - of course - just in 2 seconds. The output current was in the 20A region. This kind of circuitry is needed when FET array (many fet's in parallel) need to be switched on/off very rapidly. In this case the array consisted of 27 high current, medium voltage FET's. The gate capacitance was 0.1uF all together including the miller capacitance. The driver used the face-to-face FET topology which I have found to be quite easy to get going.

My signal generator sucks.

Need better buffer for TTL. Would something like this do? Sans oscilator



Testing small test probe, idea from here:

Put some pogos on dupont connectors. These will hook on normal pin strip and on most connectors.
