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, a phenomenon that occurs in semiconductor devices where charges become trapped in the gate oxide region, leading to device degradation. The HCI effect poses challenges in lower voltage technologies, particularly in designing high voltage I/O buffers that can operate across a wide range of supply voltages, including 3.3V, 2.5V, and 1.8V. The disclosed methods and systems aim to provide reliable bias generation in I/O buffers, thereby limiting the device drain to source voltage (Vds) and mitigating the HCI effect.
Another significant 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 design 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.
