The growing trend of the Internet of Things (IoT) involves trillions of sensors in various applications. An extensive array of parameters need to be gathered concurrently with high-precision, low-cost, and low-power sensor nodes, such as resistive (R) and capacitive (C) sensors. Single-chip channel fusion can be an effective solution, while...

Flow sensing is essential in various industrial, commercial, and biomedical applications. Although many types of flow sensors exist, thermal flow sensors are widely used due to their simple sensing elements (heaters and temperature sensors) and low fabrication costs. A low-cost interface for thermal flow sensors can then be realized with a...

This article presents a low-power eddy-current sensor interface for touch applications. It is based on a bang-bang digital phase-locked loop (DPLL) that converts the displacement of a metal target into digital information. The PLL consists of a digitally controlled oscillator (DCO) built around a sensing coil and a capacitive DAC, a...

This paper describes an interface circuit for a MEMS Coriolis mass flow sensor that combines both drive and sense circuitry. The MEMS sensor consists of a suspended resonant tube, which is read-out by comb capacitors and driven into oscillation by current flowing through a drive coil in a magnet field. The interface circuit comprises a low...

High-precision positioning often requires high speed and high resolution displacement measurements in order to compensate for the small vibrations of critical components. The displacement sensor must be precise and stable over a long period of time to avoid expensive recalibration. This requires tight mounting tolerances, which are especially...

Luo, Y. (author)
This thesis focuses on developing a high-resolution, energy-efficient smart temperature sensor. A resistor-based temperature-sensing structure is chosen as the core of the sensor. To digitize the core output, a low-noise readout circuit is developed. The design was fabricated in a standard CMOS technology, and the measurements were conducted to...

This thesis presents an incremental ?? capacitance-to-digital converter (CDC) that serves as an interface circuit for a MEMS-based pressure sensor. The thesis presents a systematic analysis of the CDC and compares different CDC architectures. A novel non-linear CDC is also proposed and analysed. Energy-efficiency of the CDC is improved by...

Yan, Y. (author)
This thesis discusses the theory, architecture design, circuit design and measurements of an ultra-low-energy reconfigurable interface circuit for resonant gas sensors. This interface circuit employs a transient measurement method. The resonant sensor is driven at a frequency close to its resonance frequency by an excitation source that is...

In this paper, we propose a novel interface concept for eddy current displacement sensors. A measurement method and a new front-end circuit are also proposed. The front-end circuit demonstrates excellent thermal stability, high resolution, and low-power consumption. The proposed idea is analytically investigated. The demodulation principle, as...
