Title: Nean-Chu Cheng: Innovator in RF Technology
Introduction
Nean-Chu Cheng is a prominent inventor based in Taipei, Taiwan. He has made significant contributions to the field of radio frequency (RF) technology, holding a total of 3 patents. His innovative work focuses on modulation devices and mixers that enhance the performance of RF receivers.
Latest Patents
One of Nean-Chu Cheng's latest patents is the "Harmonic-rejection modulation device." This device includes a phase splitter, a low pass filter, and a modulator. The phase splitter generates multiple unfiltered local oscillating signals based on a square wave. The low pass filter then filters the high-frequency components, resulting in local oscillating signals with specific phase angles. The modulator effectively modulates a baseband signal while eliminating third harmonics during the modulation process.
Another notable patent is the "Mixer for homodyne RF receiver." This mixer, developed using a CMOS process, consists of a gain stage, a switch stage, and a load stage. The gain stage processes a differential-typed RF signal to produce a first gained signal. The switch stage mixes this signal with a local oscillator (LO) signal to create a modulated signal. The load stage converts the modulated signal into a second gained signal, utilizing specific transistor configurations to optimize performance.
