Trim network for monolithic circuits and use in trimming a d/a converter |
摘要 |
There is disclosed a trim network suitable to be utilized in monolithic circuits and a method of trimming thereof to improve performance of the circuits to achieve greater yields. The network comprises at least one monolithic resistor connected across a known voltage potential and including a plurality of contacts thereon defining incremental resistances therebetween. The contacts are coupled to a common terminal via a plurality of metallic links. A desired output voltage is derived at the common terminal by open circuiting all of the links but a desired one. The voltage appearing at the common terminal can then be used for trimming a parameter of the monolithic circuit to improve the performance thereof.
