Title: Innovations of Wen-sin Liew

Introduction

Wen-sin Liew is a notable inventor based in Singapore, recognized for his contributions to the field of signal processing and digital communication. He holds 2 patents that showcase his innovative approach to technology.

Latest Patents

One of his latest patents is titled "Method and device for digital compensation of dynamic distortion in high-speed transmitters." This invention involves a transmitter that includes a shift register, a lookup table, and a digital to analog converter. The shift register is designed to receive an input signal and output delayed copies of that signal. The lookup table stores compensation values estimated based on the input signal and its delayed copies. The digital to analog converter then outputs a transmit signal based on the input signal and these compensation values, which are intended to mitigate distortion during the conversion process.

Another significant patent by Liew is the "Analog-to-digital converter for a multi-channel signal acquisition system." This invention provides an analog-to-digital converter (ADC) for a multi-channel signal acquisition system, along with methods for generating a digital output code from an analog input signal. The ADC features a sample-and-hold circuit for each input channel, a common digital-to-analog converter (DAC), and comparators for each channel that generate comparison results during each conversion cycle. A successive approximation register (SAR) is also included, which generates a digital output code based on the comparison results.
