The sensing element has a capacitance to ground that is variable as a function of the proximity of an object to the sensing element. The oscillator includes a capacitor. The control circuitry is configured to supply an excitation to the oscillator and a charge to the sensing element, and to measure the resonant frequency of the oscillator. The control circuitry provides a signal indicative of the proximity of the object to the sensing element."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Proximity detection","description":"In certain embodiments, a proximity sensor includes a sensing element, an oscillator connected to the sensing element, and control circuitry connected to the oscillator.
