Latest Patents

Marco Torrisi holds a patent for a "CMOS integration of a high bandwidth optically isolated current sensor." This invention discloses a galvanically isolated current sensor designed for power converters. The sensor comprises a package housing a first integrated circuit (IC), a light-emitting layer, an optical waveguide, a photosensing layer, and a second IC. The light-emitting layer emits light proportional to a reference current, while the optical waveguide modulates the light based on a magnetic field generated by the current to be sensed. The photosensing layer generates a photocurrent representative of the modulated light's intensity, and the second IC outputs a sense current based on this photocurrent. The optical waveguide includes polarizers and a Faraday rotator material to facilitate the modulation. Various embodiments of control circuitry for processing the sense current are also described, including a flash ADC-based system, a voltage-controlled oscillator with a high-speed counter, and a current-controlled delay line with a low-speed counter.
