Title: Innovations of Inventor Qiurong He
Introduction
Qiurong He is a notable inventor based in Andover, MA (US). He has made significant contributions to the field of digital-to-analog conversion technology. With a total of 2 patents to his name, his work has had a considerable impact on the industry.
Latest Patents
One of Qiurong He's latest patents focuses on clock signal error correction in a digital-to-analog converter (DAC). This invention includes a correction circuit for a clock, which may involve a differential clock. The error correction occurs within the DAC core through the use of replica cells that are similar to conversion cells. Instead of contributing their output to the converted signal, these replica cells provide a feedback signal to a clock receiver, which contains information for correcting the clock signal. This feedback signal is capable of correcting errors in duty cycle and crosspoint, as measured at the DAC core. Another significant patent involves an output differential stage, which features a bipolar differential output circuit. This circuit includes an input differential bipolar stage that receives an input signal and generates a differential output current. The output differential pair of bipolar transistors responds to the input signal by providing a representative output signal, while a current mirror circuit passes current from the input differential pair to the output differential pair.
