Latest Patents

Alves's latest patents include groundbreaking technologies that enhance the functionality of magnetic field sensors. One of his notable inventions is the "Circular vertical hall (CVH) sensing element with signal processing and arctangent function." This magnetic field sensor utilizes a circular vertical Hall (CVH) sensing element to produce a signal that represents an external magnetic field. It incorporates a sigma-delta analog-to-digital converter, modulators for quadrature modulated signals, and a processor that estimates the angle of the external magnetic field using these signals. An arctangent function is employed for accurate angle calculation, and a sliding window integration scheme is utilized over one or more CVH cycles.

Another significant patent is the "Circular vertical hall (CVH) sensing element with signal processing." This invention features a CVH sensing element with multiple vertical Hall elements. The output stage includes drive circuits that generate an analog signal representing the strength of the external magnetic field. An analog-to-digital converter processes this signal into a digital format, which is then used by a quadrature modulator circuit to create quadrature modulated signals. A processor stage computes the estimated angle of the external magnetic field based on these signals.
