Field effect attenuator devices having controlled electrical lengths |
摘要 |
Overlapping gate electrodes are selectively energized to vary the electrical length and thus the resistance of the conductive path through a field effect attenuator. The electrical width can also be varied to provide additional control over the resistance.
