- Figure 1. The sensor becomes part of a relaxation oscillator where one of the capacitors is charging when the other one is shorted; the two capacitors periodically swap their operation
- Figure 2. Sensor operation is simulated with a bank of 10 capacitors
- Figure 3. Circuit responses: at the top, the period is almost the same, below it, the duty cycle depends linearly on the value of C1
- Figure 4. The duty cycle response has a nonlinearity error of ±0.3 %
