The capacitance to digital converter (CDC) are being extensively used in Biomedical diagnostics, Water and level sensing applications in Industrial sector, MEMS sensor interface and plenty of hobby projects by young engineers. The basics of capacitance sensors, types of cap sensors - Floating and Grounded and their construction is discussed. Learn about the interdigitated Capacitor platform for many Gas Sensing applications and pressure sensing applications. In this course, you will learn about the following:1. What is a sensor ?2. How to design and build a capacitance sensor ?3. Use a MEMS capacitance sensor in an application. 4. Interfacing an ADC to the sensor and reading out the values.5. Touch sensing / Pressure SensingIn my research, I have proposed and demonstrated a sensitivity enhancement technique and a sensitivity tunability technique using Ring Oscillators for capacitance-based measurements. I combined both these techniques and an additional temperature calibration method and integrated the capacitance sensor in a single chip to act like a Lab-on-Chip platform. I was able to measure hundreds of atto-farad using this technique and methods. The papers based on this research work have been published in flagship IEEE Circuits and Systems Society conferences - ISCAS, MWSCAS and India's top VLSI conference - VLSID. The fundamental points used in this talk use the material from the other 4 courses offered in this platform. Do visit and enroll in the other courses to gain benefit.
