Hi readers. Using an N channel and a P channel Mosfet to control an underload from a TTL circuit, and getting a weird unexplainable result. Here is the circuit:
Looks simple enough, but look at the gate vs the drain signals:
As you can see the gate has a perfect square wave going in, but the drain ? Anything but a clean output. With or without the load. The supply feeding the source is clean, and there are no other components on the board to interfere, and I replaced the Mosfet to eliminate possibility of faulty component.
Any ideas ?
