Latest Patents

Yoo is named on the patent “Circuit for Attenuating Signal Received Through Antenna to Improve SNR, Electronic Device Including the Same, and Method for Controlling the Same.” The invention describes an electronic device with an amplifier that boosts an RF signal received through an antenna and an attenuator positioned between the amplifier and a mixer.

The device’s processor adjusts the attenuator according to the signal’s receiving power. When the power is below a threshold, the processor turns on a transistor so the amplifier’s output passes directly to the mixer. At or above the threshold, the processor uses a look-up table to control transistors, setting the attenuator’s resistance to correspond to the receiving power. This approach provides a power-dependent way to manage the signal path and support improved SNR.

Career Highlights

Yoo’s listed patent reflects work on RF circuitry and adaptive signal control, areas relevant to electronic devices that receive wireless signals. His association with Samsung Electronics Ltd. places this invention within the company’s broader electronics research and development activities.
