A recently granted patent (Publication Number: US11876089B2) discloses a voltage clamp system that includes a series of transistors, inverters, and resistor-capacitor networks designed to regulate voltage levels within an integrated circuit. The voltage clamp comprises a first transistor connected to a power supply, a second transistor linked to the first transistor and ground, and a third transistor generating a positive feedback signal based on the voltage at the gate of the second transistor. An inverter controls the operation of the first transistor based on this feedback signal, allowing the first and second transistors to create a discharge path between the power supply and ground. Additionally, a voltage divider and resistor-capacitor network filter and regulate the input signals to the inverters, ensuring stable voltage control within the system.

Furthermore, the patent also covers an integrated circuit incorporating the described voltage clamp system along with other electronic circuitry. The integrated circuit features the same configuration of transistors, inverters, and resistor-capacitor networks to maintain voltage stability and prevent overvoltage conditions. The system is designed to adjust the current flow through the transistors based on the feedback signal, ensuring efficient voltage regulation. By utilizing NMOS transistors and a CMOS inverter, the integrated circuit can effectively manage voltage levels and protect the electronic components from potential damage. Overall, the patented technology offers a comprehensive solution for voltage control within integrated circuits, enhancing their performance and reliability in various applications.
