A microelectromechanical system (MEMS) oscillator is a type of oscillator that uses a combination of microelectromechanical (MEMS) components and integrated circuits to generate a stable frequency signal. It is a type of oscillator that is used in many electronic devices, such as cell phones, computers, and other electronic equipment. The MEMS oscillator is a small, low-power device that is capable of producing a stable frequency signal over a wide range of temperatures and environmental conditions.
