    frequency modulator at ~ 150khz for speaker

    ultrasound+modulator Dear People, I am looking for a frequency modulation circuit that operates roughly in the 150kHz range. modulates audio. It need a means of providing an output of the 150kHz frequency before being modulated. so things like on the fly LC oscilation may not work. I am...

    Will my imirror circuit work?

    Dear People, I am curios if the circuit that I have combined has a chance of working? I have already made it, but the LED is getting hot, the whole thing is SMD so I don’t want to cut traces just yet. I ran some simulations, they returned within reason; error of 1 mA over all 3 leds. The...

    diffrence between flat and chekered ground plane?

    hi. does anyone know why anyone would place a ground plane, but its checkered, so there are thin bands of non-cupper dips through-out the ground plane. example would be a 10mil trace with a 30 mil spacing, so there are areas of non cupper in the ground plane are they trying to save cupper or...

    low voltage NOT gate below 0.7V

    good day. does anyone know anything about low voltage analog logic , of particular to me is how a not gate is made (the building block for everything). i dont think its possible with transistors/FET's as they have a minimum of 0.7V drop so ... If anyone could provide further hints i would...
