Title: Emanuele Lavelli: Innovator in MEMS Technology
Introduction
Emanuele Lavelli is a notable inventor based in Mandello del Lario, Italy. He has made significant contributions to the field of microelectromechanical systems (MEMS) technology. With a total of 2 patents, Lavelli's work focuses on enhancing the performance and control of MEMS oscillators and gyroscopes.
Latest Patents
One of Lavelli's latest patents is a "Driving circuit for controlling a MEMS oscillator of resonant type." This invention includes a digital conversion stage that acquires a differential sensing signal indicative of a displacement of a movable mass within the MEMS oscillator. The circuit converts the analog differential sensing signal into a digital differential signal. The processing circuitry generates a digital control signal based on the comparison between the digital differential signal and a differential reference signal, which indicates the target amplitude of oscillation. An analog conversion stage, featuring a ΣΔ DAC, converts the digital control signal into a PDM control signal, which is then filtered to produce a control signal for managing the amplitude of oscillation.
Another significant patent is for a "Microelectromechanical gyroscope having a resonant driving loop with controlled oscillation amplitude and method of controlling a microelectromechanical gyroscope." This gyroscope includes a support structure and a driving mass that moves along a driving axis. The microelectromechanical loop has a resonance frequency and a loop gain, which is maintained at a unitary value by a gain control stage. This stage includes a sampler and a transconductance operational amplifier, ensuring precise control over the gyroscope's performance.
