Latest Patents

Vassilev's latest patents include a method for determining current-voltage characteristics of devices and a device for electrostatic discharge protection. The first patent describes a method and system for evaluating the current-voltage characteristics of devices that exhibit negative resistance behavior. This innovative approach allows for accurate assessment of electrical overstress or ESD performance during voltage transitions. The method involves applying a signal with multiple amplitudes to comprehensively extract the device's IV characteristics without being limited by the system loadline.

The second patent relates to an ESD protection device, which may be a semiconductor device such as a CMOS transistor. This device features a snap-back IV characteristic that enhances its ability to withstand ESD pulses. By incorporating an additional doped region, the internal resistance of the substrate is influenced positively, resulting in a lower snap-back trigger voltage and current compared to prior art devices.
