A Magnetic Feedback-Based Δ-Σ Digitizing Interface for Giant Magnetoresistance Sensors

Tapabrata Sen et al.

Summary: Giant magnetoresistance (GMR) sensors are popular for measuring low magnetic fields due to their low-cost, easy-to-use, and high-sensitivity design. However, these sensors have limitations such as omnipolar behavior, non-linearity, and hysteresis. This paper proposes a digitizing interface based on magnetic feedback-based Delta-Sigma modulation to overcome these limitations. The interface operates the sensor at a quiescent magnetic field and provides a linear direct-digital output, allowing measurement of bipolar fields. The methodology, analysis, and performance verification of the interface are presented, along with experimental results showing reduced non-linearity and hysteresis.

Simplifying Capacitive Sensor Readout Using a New Direct Interface Circuit

Jose A. Hidalgo-Lopez et al.

Summary: This article presents a new type of capacitive DIC that is simple in terms of hardware, needing only two resistors of known value and the DP in order to make the capacitance estimation. The design has been tested for a wide range of capacitances, showing good performance with an average relative error of 0.41%, linearity errors below 0.3%, and a minimum signal-to-noise ratio of 64 dB.

An Auto-Balancing Capacitance-to-Pulse-Width Converter for Capacitive Sensors

Lakshmi Areekath et al.

Summary: The novel auto-balancing capacitance-to-pulse-width converter (CPC) presented in this paper is compatible with both single-element and differential capacitive sensors, providing a PWM signal for easy digitization and a linear output independent of sensor capacitance. The design automatically corrects non-idealities and reduces the effects of component mismatch through auto-balancing, achieving high resolution and SNR without complex analog building blocks.

Pressure Sensor with Novel Electrical Circuit Utilizing Bipolar Junction Transistor

Mikhail Basov

Summary: A high sensitivity MEMS pressure sensor chip has been developed for different pressure ranges using a novel electrical circuit design. The chip utilizes two bipolar-junction transistors and eight piezoresistors. Experimental data confirms the theoretical model's applicability, and the introduction of an amplifier allows for decreased chip size while maintaining sensitivity.
