Abstract
Methods and systems for reducing electromagnetic interference in analog circuit of a control device for an augmented reality (AR) or virtual reality (VR) system are described. An analog circuit associated with the control device may include at least one amplifier and an analog-to-digital converter coupled to an amplifier by one or more electrical conductors. Electromagnetic interference induced in the one or more electrical conductors by an external AC magnetic field may be reduced using at least one component of the control device configured to reduce the electromagnetic interference.
