A built-in self-test PLA generator
In this thesis we studied a BIST PLA generator (BPG) which generates BIST PLA layouts from the personality matrix of PLAs. We studied various BIST PLA designs and selected the design proposed by Treur, Fujiwara and Agarwal to be employed by BPG. The BIST PLA design is known to be effective in area …

A SEIR-based ADC built-in-self-test and its application in ADC self-calibration
The static linearity test is one of the fundamental production tests used to measure DC performance of analog to digital converters (ADCs). It comes with high test equipment cost. An ADC built-in-self-test (BIST) is an attractive solution. However the stringent linearity requirement for an on-chip …
