Latest Patents

One of Junjun Li's latest patents is titled "Electrostatic discharge network for driver gate protection." This invention involves an output circuit included in an integrated circuit that employs multiple protection circuits to safeguard driver devices from damage during electrostatic discharge events. One protection circuit clamps a signal port to a ground supply node upon detection of an electrostatic discharge event. Another protection circuit increases the voltage level of a control terminal to one of the driver devices during such events, thereby reducing the voltage across the driver device and preventing potential damage.

Another significant patent is the "Clamp circuit for electrical overstress and electrostatic discharge." This apparatus includes a device, a comparison circuit, and a switch. The device has a first terminal coupled to a first power supply signal and a second terminal coupled to a ground reference. The comparison circuit is designed to compare the voltage levels of two power supply signals and enable the device based on the comparison results. The switch circuit is configured to couple the power supply terminal of the comparison circuit to the appropriate power supply signal based on the voltage level comparisons.
