Amplifier turn-on speedup technique |
April 15, 2008 |
| A method of reducing the settling time of an amplifier includes providing a pre-set voltage on a high gain node of the amplifier when the amplifier is disabled. This pre-set voltage can be slightly less than the regulated voltage. In this manner, when the amplifier is enabled, the high g |

Circuit and method for quickly turning off MOS device |
March 4, 2008 |
| An OTA driving an MOS device needs to turn it off quickly to minimize overshoot during a heavy to light load state. The drains of the MOS device can be used to accelerate turning off the MOS device. A first drain is connected to the gate of the MOS device. A second drain is connected |

Method of forming a resistor having a serpentine pattern through multiple use of an alignment ke |
May 19, 1998 |
| Each die containing a resistive element which is to be trimmed has associated therewith a plurality of alignment targets. A cut mask having a trim pattern and an alignment key formed thereon is employed in a masking and etching step to trim the resistive element to a desired resistance. |

Circuit having trim pads formed in scribe channel |
January 20, 1998 |
| In accordance with the present invention, trim pads used in trimming on-chip resistive elements are formed in the scribe channels interposed between respective dice on a wafer. Metal traces connect the trim pads to their associated resistive elements formed on the dice. Thus, each trim |
