Field effect attenuator devices having controlled electrical lengths. |
| 摘要 |
<p>Overlapping gate electrodes (28,30,32) 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. <IMAGE></p> |
