Title:
集積回路によって発生された周波数を調整する方法
Document Type and Number:
Japanese Patent JP4944288
Kind Code:
B2
Abstract:
The present invention relates to a system and method for compensating IC parameters. According to an embodiment of the present invention, a die of an IC wafer is coupled with a compensation circuit that classifies the die into various types. Examples of types include fast, typical, and slow. The assigned type may be used in a special oscillator that compensates for variations from a die to a predetermined criteria. According to an embodiment of the present invention, a slow die directs a signal that moves through a relatively short path, a fast die directs a signal that moves through a relatively long path, and a typical die directs a signal that moves through a relatively medium length path in the compensation circuit. Accordingly, each die on a wafer may be coupled with a compensation circuit such that the compensation circuit selects a path of a circuit that adjusts the frequency produced by the dies to produce a batch of ICs that would meet the predetermined criteria for the vast majority of the dies. A large number of useable Ics would be produced by adjusting the frequency produced by the ICs which would conventionally not meet the predetermined criteria to a frequency that does meet the predetermined criteria.
