Title: Innovations of Xiaoping Chen
Introduction
Xiaoping Chen is a notable inventor based in Hangzhou, China. He has made significant contributions to the field of semiconductor technology, particularly in the design of integrated circuits. With a total of 3 patents to his name, Chen's work has had a considerable impact on the industry.
Latest Patents
Chen's latest patents include a "Clock Dividing Frequency Circuit" and a "Control Circuit and Power Management Integrated Circuit." The clock dividing frequency circuit features a controlled current source that generates a driving current based on a dividing frequency control signal. It also includes a ramp signal generating circuit that produces a ramp signal with a slope that varies according to the driving current. This ramp signal is reset according to pulses of a dividing frequency clock signal. The dividing frequency pulse generating circuit then generates the dividing frequency clock signal through a dividing frequency operation based on the ramp signal and a system clock signal.
The control circuit patent focuses on generating a switching control signal to manage the operations of a power switch in a power stage circuit. It consists of a first control loop that receives a voltage feedback signal to generate a compensation signal. Additionally, a voltage regulating circuit generates a second compensation signal based on the output voltage signal of the power stage circuit during different time periods. The control and driving circuit processes these compensation signals along with a sense voltage signal to produce an OFF signal and a switching control signal.
