    FET oscillator - HELP!

    Hello, here's an "idea" of my circuit. The oscillation occurs because the transmission line between the gates transforms the input reactance of one transistor to its negative value. Like this there is a point of virtual ground in the middle of that line and so at the gates and at the drains the...

    FET oscillator - HELP!

    Hello everybody, i am trying to build a FET oscillator and i have a strange problem with the bias. I bias the FET independently at gate and at the drain. At some point, i cannot change my gate bias anymore (to a more positive value, say at around -0.6V i cannot go to -0.5 anymore) unless i...
