Abstract
An apparatus including a first signal generator of a force sensing circuit to output a first excitation (TX) signal on a first terminal and a second TX signal on a second terminal. The first terminal and the second terminal are configured to couple to a first force sensor and a reference sensor. The apparatus includes a first receiver channel coupled to a third terminal and a fourth terminal. The third terminal is configured to couple to the first force sensor and the fourth terminal is configured to couple to the reference sensor. The force sensing circuit is configured to measure a first receive (RX) signal from the first force sensor via the third terminal and a second RX signal from the reference sensor via the fourth terminal. The force sensing circuit is configured to measure a force value indicative of a force applied to the first force sensor.
