Title: Yiyu Shen: Innovator in RF Technology

Introduction

Yiyu Shen is a prominent inventor based in Delft, Netherlands. He has made significant contributions to the field of radio frequency (RF) technology, holding 3 patents that showcase his innovative approach to digital transmission and modulation.

Latest Patents

One of his latest patents is titled "Digital transmitter with high linearity for wideband signals." This invention features an RF transmitter that includes common-gate and common-base configured output stages. It utilizes a digitally controlled current source with multiple unit cells connected to the output stages. Each unit cell comprises a current source that drives the output stages based on input signals. Additionally, the current source includes a diversion path to provide a diversion current to a voltage source with a lower voltage than the drain or collector terminals of the transistors in the output stages.

Another notable patent is the "RF-DAC based phase modulator." This invention is a wideband, frequency agile RF digital-to-analog converter that includes three RF-DACs. Each RF-DAC is configured to upconvert an input I/Q digital baseband signal pair to a local oscillator frequency, with specific phase relationships between the sets of LO clocks. The combined output of these RF-DACs reinforces the fundamental LO component while canceling unwanted harmonics.
