METHODS AND APPARATUS FOR TRIMMING ELECTRICAL DEVICES |
摘要 |
Trimming methods and apparatus are disclosed for selectively removing resistance between first and second nodes in an electrical device, including trim circuits comprising a resistor and a diode formed in the resistor body having a conductive portion which may be selectively melted to short the resistor. A multi-bit trim cell is disclosed having trim cells individually comprising a resistor with a diode formed in the resistor body for selectively shorting the resistor, and a fuse for selectively disconnecting the diode from a trim pad.
