  • Patent number: 11923429
    Abstract: A semiconductor device and method for forming the semiconductor device are provided. In some embodiments, a semiconductor substrate comprises a device region. An isolation structure extends laterally in a closed path to demarcate the device region. A first source/drain region and a second source/drain region are in the device region and laterally spaced. A sidewall of the first source/drain region directly contacts the isolation structure at a first isolation structure sidewall, and remaining sidewalls of the first source/drain region are spaced from the isolation structure. A selectively-conductive channel is in the device region, and extends laterally from the first source/drain region to the second source/drain region. A plate comprises a central portion and a first peripheral portion. The central portion overlies the selectively-conductive channel, and the first peripheral portion protrudes from the central portion towards the first isolation structure sidewall.

  • Publication number: 20240072672
    Abstract: A control method is in use of an interleaved power converter with first and second power stages for generating an output power source. A compensation is generated in response to a feedback signal and a reference voltage, and the feedback signal represents the output power source. The output power of the first power stage is controlled to supply to the output power source in response to the compensation signal. The operation status of the second power stage is switched in response to the compensation signal and the feedback signal, and is prevented from being switched when the feedback signal is beyond a stable range covering the reference voltage.
