Latest Patents

One of Sanghun Sim's latest patents is titled "Protection circuit in electronic device and method therefor." This invention provides an electronic device and method designed to prevent burnout due to overcurrent. The device includes a power amplifier that amplifies a transmission signal, a battery that supplies a bias voltage to the power amplifier, and an overcurrent protection circuit. This circuit is equipped with a configurer to set a reference current value, a measurer to assess the bias current value, a comparator to compare the measured value with the reference, and a controller to manage the bias voltage based on the comparison results.

Another significant patent is the "Apparatus for preventing component burnout in electric device and method thereof." This invention outlines a method for an electronic device that generates a reference signal with a specific frequency. It mixes this reference signal with an input signal for transmission and amplifies the power. If the frequency of a signal acquired at any point deviates from a designated frequency band, the apparatus outputs a control signal to turn off the amplification, thereby preventing burnout of the power amplifier.
