Latest Patents

One of his latest patents is titled "Method and system for mitigating hot carrier injection effect in a semiconductor circuit." This invention addresses the hot carrier injection (HCI) effect, which is a significant issue in semiconductor devices. The HCI effect occurs when charges are trapped in the gate oxide region, leading to device degradation. This phenomenon poses challenges in designing high voltage, wide range I/O buffers, especially in lower voltage technologies. The disclosed methods and systems aim to provide reliable bias generation in I/O buffers or other semiconductor circuits, effectively limiting the device drain to source voltage (Vds) to mitigate the HCI effect.

Another notable patent is the "Method for implementing an I/O buffer." This invention describes an I/O buffer that operates without an auxiliary power supply (VCCAUX). The I/O buffer includes connections to a VCCO power supply, a VCCINT power supply, a reference voltage, and a VCCO detection circuit linked to a bias generation circuit. Additionally, it features a transmitter circuit connected to the bias generation circuit and a receiver circuit linked to an I/O pad.
