Abstract

Aspects are directed to a MEMS device configurable to receive signals from a first, a second, a third, and a fourth signal source operating at a first, a second, a third, and a fourth frequency, respectively. The MEMS device may be configured to combine the first signal with the second signal generating a first combined signal, and to combine the third signal with the fourth signal generating a second combined signal. The first combined signal may be coupled to the first terminal of the MEMS device while the second combined signal may be coupled to the second terminal of the MEMS device. The first common terminal may be configured to produce an output associated with the second and fourth frequencies. The MEMS device may be further configured to derive from the produced output a signal indicative of nonlinearities or of changes in capacitance related to the MEMS device.
