Abstract
A frequency selection device comprises an oscillator, which comprises a resonator mass which is connected by a spring arrangement to a substrate, and a piezoresistive element for controlling oscillation of the resonator mass, which comprises a piezoresistive element connected to the resonator mass. A current is driven through the piezoresistive element to control oscillation of the resonator mass. An input is provided for coupling a signal from which a desired frequency range is to be selected, to the resonator mass; and a detector is used for detecting a signal amplified by the oscillator.
