Lots of explanation related to technique, output voltage, offset, the proposed circuit, and circuit are described inside this paper. The following are grabbed from the paper:

Design and Implementation of Capacitive Sensor Readout Circuit on Glass Substrate for Touch Panel Applications Tzu-Ming Wang1 and Ming-Dou Ker1,2 1 2 Institute of Electronics, National Chiao-Tung University, Hsinchu, Taiwan. 4 shows the simulated result of the proposed circuit under the non-touch event with VDDA = VDDB = 10 V, Vref = 6 V, Va1 = 6.15 V, Va2 = 6.36 V, Va3 = 6.6 V, Va4 = 6.8 V, Clk1 = Clk2 = 100 kHz, C1 = 8 pF, and C2 = 1 pF. The proposed readout circuit for touch panel application on glass substrate can be integrated in the active matrix LCD (AMLCD) panels to increase the sensing resolution of touch panel for SOP applications.

Even more, the paper gives you discussion things like measurement setup, readout circuit, sensor, and sensor readout circuit.
