Title: Innovations of Cheng-Feng Chung
Introduction
Cheng-Feng Chung is a notable inventor based in Taipei, Taiwan. He has made significant contributions to the field of voltage regulation and pulse width modulation. With a total of 2 patents, his work has advanced the technology used in voltage regulators.
Latest Patents
Chung's latest patents include a "Voltage regulator and pulse width modulation signal generation method thereof." This method involves providing an output sense signal, a first ramp signal, and a second ramp signal. The first time point of the first ramp signal crossing with the output sense signal determines the start point of the ON-time of a PWM signal. The second time point of the second ramp signal crossing with the output sense signal determines the end point of the ON-time of the PWM signal. Additionally, the first ramp signal is reset to a reference voltage at the first time point and maintained at that voltage, while the second ramp signal ramps up from the start point of the ON-time.
Another significant patent is the "Method for improving voltage identification transient response and voltage regulator." This method continuously senses the inductor current of the voltage regulator to output a current sense signal. During steady state operation, the current sense signal is sampled to obtain a droop control signal. After entering a VID transient period, the sampling result is held to provide the droop control signal, which is then used to regulate the output voltage of the voltage regulator.
