    • Apparatus is used in sensing a measured input. The apparatus includes a capacitor with a capacitance that varies non-linearly in response to the measured input, and a circuitry that derives, from the capacitance, a signal that varies substantially linearly with the measured input. The capacitor includes a first electrode, a second electrode, and a gap defined by a space between the electrode. The circuitry includes an amplifier with a first input terminal in electrical communication with the first electrode, a second input terminal, and an output terminal in electrical communication with the second electrode. The capacitance of the capacitor varies as an inverse of the gap of the capacitor, the gap of the capacitor varies in response to changes in the measured input, and the signal is derived from an output of the amplifier.
