  • Patent number: 12272633
    Abstract: An isolation capacitor structure reduces the likelihood of breakdown in the passivation layers by physically re-shaping or dividing the top plate of the isolation capacitor into two segments. In that way, the electric field is driven down and away from the passivation surfaces. One embodiment utilizes a series capacitor formed by the top metal plate of the capacitor and an additional “top hat” plate above the top metal plate that redirects the fields into the main isolation capacitor. Vias may be included between the top hat plate and the top metal plate. Another approach reshapes the top plate to have an integrated top hat structure and achieves similar results of directing charge down and away from the passivation layer surface breakdown paths.

  • Patent number: 12261635
    Abstract: Radio frequency front-end systems with filter reuse. In certain embodiments, a front-end system includes a filter, a low noise amplifier (LNA), and a switch interposed between the filter and an input to the LNA. In a first state of the switch, the filter serves to filter a radio frequency signal that is amplified by the LNA. The front-end system further includes a power amplifier that is coupled to the switch. Additionally, in a second state of the switch, the filter serves to filter an amplified radio frequency transmit signal provided by the power amplifier. Accordingly, a filter along a receive path of the front-end system is reused for transmit.

  • Patent number: 12261725
    Abstract: An isolated gate driver includes a first input terminal to receive gate information and one or more input terminals to receive configuration information. A modulation circuit generates a modulated signal having four possible states, each of the four possible states corresponding to a different unique pair of values of the gate information and the configuration information. The modulation circuit represents two of the states using on-off keying (OOK) while the configuration information is at a first value and represents two of the states as a modification to the OOK modulation based on the configuration information being at a second value. The modulated signal is sent over an isolation communication channel coupling a transmitter and receiver of the isolated gate driver.
