If you use a pic to generate a frequency in the khz range on a Infrared led which is driven by a fet how do you calculate the input frequency on the gate required to compensate for the turn on delay present on the fet to output x frequency ?
For example if i wanted to have a modulate a infrared led at 38khz how would i calculate the fet gate input frequency required to achieve the 38khz output ?
