Latest Patents

Won Seob Lim holds a patent for an "Average power tracking mode power amplifier using dual bias voltage levels." This invention includes a Power Amplifier (PA), a first Direct Current (DC)-DC voltage converter, and a second DC-DC voltage converter. The PA is designed with a driver stage that operates on a first drive voltage and a main amplification stage that functions on a second drive voltage. The first DC-DC voltage converter generates the first drive voltage from the power voltage, ensuring it is equal to or higher than the power voltage. This voltage is then applied to the driver stage. Meanwhile, the second DC-DC voltage converter produces a second drive voltage that is higher than the first drive voltage, which is applied to the main amplification stage. This innovative design allows for improved power tracking and efficiency in power amplifiers.
