  • Patent number: 11955960
    Abstract: The invention uses the control circuit formed on the silicon wafer to detect the leakage current of transistor formed on the depletion mode GaN wafer and then adjust the gate voltage of the depletion mode GaN transistor according to the detected leakage current. Essentially, the gate voltage is reduced or viewed as made more negative when the detected leakage current is larger a specific value. Thus, the gate voltage can be gradually adjusted to approach a specific threshold voltage that right block the leakage current. In other words, by making the gate voltage more negative when non-zero leakage current is detected and even by making the gate voltage more positive when zero leakage current is detected, the depletion mode GaN transistor can be adjusted to have an acceptable or even zero leakage current, a high reaction rate and an optimized efficiency.

  • Publication number: 20240086014
    Abstract: An electronic device may have a display with touch sensors. One or more shielding layers may be interposed between the display and the touch sensors. The shielding layers may include shielding structures such as a conductive mesh structure and/or a transparent conductive film. The shielding structures may be actively driven or passively biased. In the active driving scheme, one or more inverting circuits may receive a noise signal from a cathode layer in the display and/or from the shielding structures, invert the received noise signal, and drive the inverted noise signal back onto the shielding structures to prevent any noise from the display from negatively impacting the performance of the touch sensors. In the passive biasing scheme, the shielding structures may be biased to a power supply voltage.
