hi guys i have currently built a a colpits oscillator running at 10mhz. it is driving a IXFN140N30P mini brick mosfet directly through a 10 ohm resistor but the output wave is only 50khz the waveform is at the drain a square wave from the front but from the trailing edge it slopes down to just above ground almost like a sawtooth wave i. am using a 2uh inductor as a load current limiting resistor my point i am trying to get to is. what would cause it to run at a lower frequency than the one at the gate and what would cause such a weird waveform if you could help i would be greatful
