Introduction

Jingran Qu is a notable inventor based in Taipei County, Taiwan. He has made significant contributions to the field of electronics, particularly in the development of innovative loop filters and delay line technologies. With a total of 3 patents to his name, Qu continues to push the boundaries of engineering and technology.

Latest Patents

One of Qu's latest patents involves loop filters. These loop filters are designed with a first resistor that has a first terminal coupled to a first node and a second terminal coupled to a second node. A first capacitor is connected between the second node and a ground voltage, while a second resistor has a first terminal linked to the first node and a second terminal connected to a third node. An operational amplifier is included, featuring a non-inversion input terminal linked to the second node, an inversion input terminal connected to the third node, and an output terminal. Additionally, a second capacitor is coupled between the output terminal of the operational amplifier and the third node.

Another significant patent by Qu is related to delay lines and delay lock loops. This invention comprises first and second delay arrays along with a multiplexer. The first delay array receives a clock signal and a delay control signal, which it uses to delay the clock signal and output a first delay array clock signal. The second delay array receives a power control signal, the first delay array clock signal, and the delay control signal. It can be turned on or off based on the power control signal. When activated, the second delay array delays the first delay array clock signal to produce a second delay array clock signal. The multiplexer then selects between the first and second delay array clock signals based on a selecting control signal.
