Introduction

Jau Horng Chen is a notable inventor based in Chandler, AZ (US). He has made significant contributions to the field of wireless communication, holding a total of 3 patents. His work focuses on enhancing the efficiency and performance of communication systems.

Latest Patents

Chen's latest patents include a wireless communication unit and an integrated circuit, along with a method of power control for a power amplifier. The wireless communication unit features a transmitter with a forward path that includes a power amplifier (PA) and a feedback path designed to feed back a portion of the output signal from the PA. This configuration forms a constant gain tracking (CGT) loop, which is crucial for maintaining signal integrity. Additionally, the feedback path incorporates an adaptive predistortion logic module that operates outside the CGT loop, creating an adaptive pre-distortion (APD) loop. This innovative design allows for precise control of the gain offset of signals routed through the system.

Another significant patent involves adaptive pre-distortion with interference detection and mitigation. This invention includes methods and electronic systems that generate a pre-distorted data sample by combining an input sample with a gain value derived from a gain lookup table. The resulting amplified analog signal is then compared to a feedback sample, allowing for the generation of a difference indicator. This process enables the continuous updating of gain values, enhancing the overall performance of the communication system.
