This paper is a continuation of a previous work with regard to the direct connection of differential sensors to microcontrollers without using intermediate electronics between them. This paper focuses on the measurement of differential capacitive sensors, whereas the previous work dealt with the resistive counterparts. The proposed circuit is analyzed, and the main limitation seems to be the fact that the magnitude of the input parasitic capacitances of the microcontroller is similar to or even higher than the sensor capacitances. Methods to overcome this limitation are proposed, particularly when measuring low-value differential capacitive sensors such as microelectromechanical system (MEMS) sensors. Experimental tests of the circuit have been carried out by measuring a commercial capacitive accelerometer working as a tilt sensor. Although such a sensor has a low value (1.5 pF) and low sensitivity (0.105 pF/g), the measurement has shown a nonlinearity error of 1% full-scale span (FSS), which is a remarkable value considering the simplicity of the circuit.

Ferran ReverterTwo noteworthy events associated to the physics of thermal sensors were demonstrated and announced in 1821, exactly two hundred years ago. The first event was the Seebeck effect, which led to the development of thermocouples. The second was the study of the thermal dependence of the resistivity of pure metals, which led to the design of resistance temperature detectors (RTD). Sensors’ science and technology has experienced remarkable advances in the last decades, but these two types of thermal sensors, whose physics were announced 200 years ago, are still nowadays the main sensor technology in many industrial applications that require the measurement of extreme temperatures. In such a $200^{th}$ anniversary, this tutorial aims to explain the operating principle, subtypes, input-output characteristic, limitations, and new trends under research of the four main types of thermal sensor: RTDs, thermistors, silicon sensors, and thermocouples. These are also compared with each other, highlighting the main advantages and disadvantages of each sensor technology.
Journal Article
Ferran ReverterThis paper reviews the direct connection of sensors to microcontrollers without using any analogue circuit (such as an amplifier or analogue-to-digital converter) in the signal path, thus resulting in a low-cost, lower-power sensor electronic interface. It first discusses the operating principle and explains how resistive and capacitive sensors with different topologies (i.e., single, differential and bridge type) can be directly connected to a microcontroller to build the so-called direct interface circuit. It then shows some applications of the proposed circuits using commercial devices and discusses their performance. Finally, it deals with the power consumption and proposes some design guidelines to reduce the current consumption of such circuits in active mode.

Ferran Reverter was born in Llagostera, Spain, in 1976. He received a B.Sc. degree in Industrial Electronic Engineering from the University of Girona (Girona, Spain) in 1998, an M.Sc. degree in Electronic Engineering from the University of Barcelona (Barcelona, Spain) in 2001, and a Ph.D. degree in Electronic Engineering from the Universitat Politècnica de Catalunya (UPC) (Barcelona, Spain) in 2004. Since 2001, he has been with the UPC, where he is an Associate Professor in Analog Electronics, Digital Systems, and Sensors. From 2018 to 2023, he was also a Course Instructor in Electronic Instrumentation with the Open University of Catalonia (UOC). He was a visiting Post-Doctoral Researcher with the Delft University of Technology (Delft, The Netherlands) from 2005 to 2007, and with Imperial College London (London, UK) in 2012. His current research interests include interface electronics for smart sensors, power-processing circuits for autonomous sensors, and MOSFET thermal sensors for IC testing. He was awarded “Outstanding Reviewer” from the IEEE Instrumentation and Measurement Society three times (2014, 2018, and 2019). He was an Associate Editor of the IEEE Sensors Journal (2015-2022) and IEEE Transactions on Instrumentation and Measurement (2018-2022).
