Abstract
Dither circuitry includes harmonic signal generation circuitry configured generate a high order even harmonic of a base excitation signal. The dither circuitry also includes a combiner configured to generate a dithered excitation signal based on the high order even harmonic and the base excitation signal. The dither circuitry further includes an output terminal configured to output the dithered excitation signal to a sensor device.
