Title: Innovations by Yingyi Liu

Introduction

Yingyi Liu is a notable inventor based in Hefei, China. He has made significant contributions to the field of electronics, particularly in the development of analog-to-digital converters and voltage regulators. With a total of 3 patents to his name, Liu's work has had a considerable impact on the industry.

Latest Patents

Liu's latest patents include an Analog to Digital Converter (ADC), an integrated circuit that incorporates the ADC, and an ADC method. The ADC features an input adjustment buffer stage, a sub-ADC, and a sample switch. The sample switch connects the output node of the input adjustment buffer stage to the input node of the sub-ADC. When the sample switch is opened, the input adjustment buffer stage alternates between two work states based on a predetermined rule, adjusting the input voltage signal accordingly. When closed, the sample switch allows the input adjustment buffer stage to provide an adjusted voltage signal to the sub-ADC, which then performs the analog-to-digital conversion. Additionally, Liu has developed a stabilized voltage regulator that includes a pass transistor, an operational amplifier, and a voltage divider circuit. This regulator generates a controlled output voltage based on a feedback voltage, ensuring stability and efficiency.
