Title: Kun Wang: Innovator in Digital Power Management Solutions
Introduction
Kun Wang is a notable inventor based in Berkeley, CA, who has made significant contributions to the field of digital power management. With a focus on low-power solutions for handheld devices, he has been awarded 2 patents that showcase his innovative approach to power supply technology.
Latest Patents
One of Kun Wang's latest patents is a digital pulse-width modulator based on a non-symmetric self-oscillating circuit. This low-power digital pulse-width modulator (DPWM) architecture is designed for high-frequency dc-dc switch-mode power supplies (SMPS). It is particularly well-suited for integration into power management systems of small handheld devices. The DPWM operates in a stand-alone mode without the need for an external clock, and it occupies a smaller silicon area compared to other DPWM solutions. Additionally, it boasts low power consumption and provides excellent linearity of the input-to-output characteristic, which is not typical for other architectures.
Another significant patent is the digital pulse frequency/pulse amplitude (DPFM/DPAM) controller for low-power switching power supplies. This digital controller is designed for dc-dc switching converters and can operate efficiently under light load conditions. It is suitable for use in switch-mode power supplies, providing regulated output voltage for handheld devices and other low-power electronics. The DPFM/DPAM can create long time intervals compared to the propagation time of digital logic by utilizing a ring oscillator with two sets of delay cells and two signals racing around the ring.
