A Low-Power Thermal-Based Sensor System for Low Air Flow Detection.

Analog Integr Circuits Signal Process 2016 Nov 8;89(2):425-436. Epub 2016 Sep 8.

School of Public Health, The University of Alabama at Birmingham, Birmingham, Alabama 35294, USA,

Being able to rapidly detect a low air flow rate with high accuracy is essential for various applications in the automotive and biomedical industries. We have developed a thermal-based low air flow sensor with a low-power sensor readout for biomedical applications. The thermal-based air flow sensor comprises a heater and three pairs of temperature sensors that sense temperature differences due to laminar air flow. Read More

A 13-bit Noise Shaping SAR-ADC with Dual-Polarity Digital Calibration.

Analog Integr Circuits Signal Process 2013 Jun;75(3):459-465

School of Electrical and Computer Engineering, Georgia Institute of Technology.

We present a new noise shaping method and a dual polarity calibration technique suited for successive approximation register type analog to digital converters (SAR-ADC). Noise is pushed to higher frequencies with the noise shaping by adding a switched capacitor. The SAR capacitor array mismatch has been compensated by the dual-polarity digital calibration with minimum circuit overhead. Read More
