Dual gate mosfets

Now for the final step in the present journey. The dual gate mosfet. The audio amp in my last post used a bias adjustment and the signal on the same element of the mosfet. The dual gate separates these two functions and enables the use of two inputs or a bias and signal  Discovering and using the dual gate mosfet will be the objective. Years ago I bought a few of them to use in a short wave receiver, The new old stock prices will give you sticker shock. Fortunately they are still avaiable in surface mount. that will be the subject of the next post.

  2. Sorry, it is gone. Google "fact checkers" removed several of my post. They sent me a note saying the posts were being removed without any explanation other than I had violated a policy when I posted them?
