A method that comprises converting a first electrical signal to a second electrical signal using a converter coupled between a micro-mechanical structure and an analog-to-digital converter (ADC). The method also comprises actuating a switch to selectively interpolate at least one datum between two neighboring converted second electrical signals based on a selected clock signal, wherein the selected clock signal is one of a plurality of clock signals, each clock signals of the plurality of clock signals has a corresponding frequency, and the selected clock signal corresponds to an operating mode of the micro-mechanical structure.
