An URL to this in article format would be very nice. Videos are sure trendy but articles are easier to read, also articles can include links to the featured products.
"distributed resistance" i thought he said a couple times, around 3:35-4:00...but he is talking about distributed capacitance, no? Or most importantly the gate-source cap and dominant effect of gate-drain miller capacitance when in common source operation
Thank you very much! I've noticed that when using discrete npn and pnp transistor to drive a MOSFET the ON and Off graph plot is different; the off state has like a downward curve while the on graph plot is like a stright vertical-horizontal line. Can you tell something about it, please?
The biggest need comes from when you're trying to feed the same signal into multiple devices, but also when you convert from a voltage controlled to current controlled component you may need some method for boosting signal. A purely voltage controlled signal can lack the necessary amperage to drive a gate/receiver.
I dont know-- his graph shows output current so I thought the capacitor is to represent a load. On the other hand, its in a good place to act as a decoupling capacitor.
@@RRVideosAndSound I think it connected to proper nodes. It looks to be simply decoupling capacitor, shouldn't really be included in the schematic, as it is non essential, but in high current applications, is probably important to have it close to the BJTs.
These are excellent suggestions. Very often discrete gate drive ciruits work as well or better than integrated drivers for a fraction of the price.
Thanks for the summary. I'm an EE student and general info like this helps me to get my bearings for projects..
This is an excellent video on gate drives. I am presently using one the drive he presented in one of my designs
Bots bitches

Which transistor can be used for 600 KHz switching speed ?
Very very vr vr... Gooooooood. Real.

Im still unsure on the necessity of drivers. Do you only need them in high power applications?
In 200-500 kHz frequency application they could be necessary. For your information:

Very nice
5:20 ffs where is Q3?
Looks like C1 is not connected to the proper nodes.
Should i be connected to the output?
