Multivariate calibration on a low transistor-count sensor signal processor

This paper presents the implementation of multivariate calibration, which is a Chemometrics technique, on a 16-bit precision, low transistor-count serial sensor signal processor. The primary advantage of the proposed processor is its small area consumption due to the one-bit-a-time serial processing architecture and the off-chip memory for data and instruction storage. The processor chip is fabricated in the low cost CMOS technology, and yields compact silicon area and low power consumption, also demonstrating the program flexibility for sensor signal processing capabilities such as in-field self-calibration for the biomedical/chemistry sensor systems-on-a-chip.
