Title: Lu Chen: Innovator in Analog-to-Digital Conversion Technologies

Introduction

Lu Chen is a prominent inventor based in Hong Kong, CN, known for his contributions to the field of analog-to-digital conversion technologies. With a total of 2 patents, he has made significant advancements that enhance the performance and stability of electronic systems.

Latest Patents

One of Lu Chen's latest patents is the "Automatic Gain Control (AGC) for On-Off Shift-Keying (OOK) Receiver." This innovative design features a non-continuous AGC that sets gain at the beginning of each frame, locking the gain setting for the remainder of the frame. This mechanism prevents OOK data from causing AGC loop instability, ensuring reliable data transmission. The AGC controller initializes the gain settings for a Low-Noise Amplifier (LNA), Low-Pass Filter (LPF), and a Programmable Gain Amplifier (PGA) in series, which powers a rectifier generating a voltage output for a data decision circuit.

Another notable patent is the "Multi-Stage Hybrid Analog-to-Digital Converter." This hybrid ADC employs multiple stages, with the first and final stages utilizing a Successive-Approximation Register (SAR) ADC to generate the Most-Significant-Bits (MSBs) and the Least-Significant-Bits (LSBs). The middle stages utilize a faster flash ADC to produce the middle binary bits, which are then processed to enhance the overall precision of the converter to 14-bit.
