Title: The Innovations of Inventor Hyung-Ki Ahn

Introduction

Hyung-Ki Ahn is an accomplished inventor based in Seoul, South Korea. With a total of three patents to his name, Ahn has made significant contributions to the fields of electronics and signal processing while working at Samsung Electronics Co., Ltd.

Latest Patents

Among his notable inventions are a frequency divider, a mode-switching low-noise amplifier, and a wide-band RF receiver.

1. **Frequency Divider**: This invention includes a prescaler and multiple modulus dividers that are commonly coupled to the prescaler. The prescaler generates intermediate frequency signals with the same phase difference in response to an oscillation frequency signal and operates at a first frequency. The modulus dividers then divide these intermediate frequency signals according to a specified ratio, providing various division frequency signals based on a control signal. Notably, the modulus dividers function at a second frequency, which is lower than the first frequency.

2. **Mode-Switching Low-Noise Amplifier and Wide-Band RF Receiver**: This innovative device features an input unit, an output unit, and a bias voltage generator. The input unit amplifies incoming signals to produce an amplified signal, while the output unit can operate in either an oscillation mode or an amplification mode based on a control signal. This allows the device to generate an output signal with a center frequency that matches a target frequency. The bias voltage generator supplies the necessary input bias voltage to adapt to the operational mode dictated by the control signal.
