Latest Patents

Sung Jae Oh holds a patent for a "Dynamic bias modulator with multiple output voltage converter and power amplification apparatus using the same." This invention includes a power amplification apparatus that features a multiple output bias voltage generation unit, a dynamic bias modulator, and a power amplifier. The multiple output bias voltage generation unit generates first and second bias voltages using an inductor coupled between an input voltage and a plurality of capacitors. The capacitors are connected to the inductor in a non-overlapping manner. The dynamic bias modulator outputs the first bias voltage or the second bias voltage as a variable bias voltage based on results of comparing the voltage of an envelope signal of an RF signal to an envelope reference voltage. The power amplifier is biased in response to the variable bias voltage, amplifies the power of the RF signal, and outputs the amplified RF signal to an antenna. This patent showcases his innovative approach to improving power amplification systems.
