Latest Patents

Yang Lin's latest patents include innovative designs for micromechanical resonant switches and charge pumps. One of his notable inventions presents a circuit of N micromechanical resonant switches, which mimics a Dickson charge pump. This design amplifies an input voltage to an output voltage of N plus 1 times the input voltage while avoiding the diode voltage drop and breakdown voltage limitations of conventional CMOS-based charge pumps. Key aspects of this technology include the long cycle lifetime of resonant micromechanical switches, which can operate for 173.9×10 cycles, significantly surpassing non-resonant switches. Additionally, the use of gated-sinusoid drive excitation allows for a charging period that is independent of the resonance frequency of the resoswitch. This innovation lowers the required drive and DC-bias voltages, making it suitable for applications requiring large voltages, such as MEMS-based timing references.

Another patent focuses on MEMS resonant switches and their applications in power converters and amplifiers. This invention features a modally driven oscillating element that periodically contacts one or more electrical contacts, functioning as a resonant switch with high quality factors, typically above 10,000 in air. The design improves the bandwidth of the switch through periodic constrained contacting, enabling the implementation of power amplifiers and converters that closely approach ideal performance. Integrated circuit fabrication techniques allow for the construction of the resoswitch alongside other integrated CMOS elements, resulting in highly compact switching devices.
