In this study, a low-power analog integrated classifier for biomedical applications based on an ANN is introduced. The proposed architecture consists of four analog circuits as building blocks. All circuits operate in sub-threshold region in order to achieve low-power consumption. Post-layout simulations using the Cadence IC Suite and the TSMC 90 nm CMOS technology demonstrate that the proposed analog classifier operates properly with good sensitivity. The implemented classifier is trained using software and it is compared with related classifiers. It can be used as a building block for biomedical monitoring.

摘要

In this study, a low-power analog integrated classifier for biomedical applications based on an ANN is introduced. The proposed architecture consists of four analog circuits as building blocks. All circuits operate in sub-threshold region in order to achieve low-power consumption. Post-layout simulations using the Cadence IC Suite and the TSMC 90 nm CMOS technology demonstrate that the proposed analog classifier operates properly with good sensitivity. The implemented classifier is trained using software and it is compared with related classifiers. It can be used as a building block for biomedical monitoring.
