Microelectromechanical resonator with improved electrical features

An electronic device, comprising:

• a timing circuit is configured to generate a clock signal based on oscillatory movement of first and second flexing arms of a MEMS resonator, the MEMS resonator including:
• a substrate;
• a moving structure suspended above said substrate and having its main extension in a horizontal plane formed by a first and a second horizontal axis which are orthogonal to one another, the structure comprising a first and a second flexing arm, parallel to one another and extending along the second horizontal axis, said first and second flexing arms being coupled at their respective ends by a first and a second transverse joining element, the first and second transverse joining elements having an extension along the first horizontal axis to forming an internal window with the first and second flexing arms;
• a first electrode structure positioned outside said window and capacitively coupled in said horizontal plane to the moving structure;
• a second electrode structure positioned inside said window and capacitively coupled in said horizontal plane to the moving structure, one of said first and second electrode structures having the function of causing an oscillatory movement of said first and second flexing arm in opposite directions along said first horizontal axis, at a corresponding resonance frequency, and the other of said first and second electrode structures having the function of detecting said oscillation;
• and
• a suspension structure configured to suspend said moving structure above the substrate, said suspension structure including a suspension arm extending inside said window between said first and second transverse joining elements, and an attachment arrangement coupled to said suspension arm and to said substrate, the attachment arrangement positioned centrally in said window near said second electrode structure;
• and
• an application circuit coupled to the timing circuit to receive said clock signal, the application circuit configured to execute one or more applications utilizing timing based on the clock signal.
