Abstract
Electronic circuitry is described. The electronic circuitry includes a first microelectromechanical system (MEMS) structure that exhibits a first frequency response in a voice frequency range and that captures a first signal. The electronic circuitry also includes a second MEMS structure coupled to the first MEMS structure. The second MEMS structure exhibits a second frequency response in an ultrasound frequency range and captures a second signal. A combination of the first frequency response and the second frequency response achieves a target frequency response in a combined frequency range
