Many info related to virtual ground, capacitive sensor, interface, electrostatic forces, noise, power, capacitive sensor interface, sensor, phase, and demodulator are described in the presentation. Inside this presentation you can learn information such as correlated double sampling, position, double sampling, signal, position sense circuits, sampling, multiplier, capacitors, and filter.
The presentation presents explanation around circuits, offset, position sense, sensing parasitics, drift reduction, bootstrapping, sense circuits, sensing, and gain. These are grabbed from this presentation:
