Field effect tetrode : ウィキペディア英語版 | Field effect tetrode The field effect tetrode is a solid-state device, constructed by creating two field effect channels back-to-back, with a junction between. It is a four terminal device with interesting properties. It does not have specific gate terminals since each channel is a gate for the other, the voltage conditions modulating the current carried by the other channel. ==Current voltage relationship== Where the current in the first channel is , the current in the second channel is , the voltage of the first channel is - and in the second channel - we have:
and
Where the are the low-voltage conductance of the channels and is the pinch-off voltage (assumed to be the same for each channel).
