Title: The Innovative Contributions of Sam S Ochi
Introduction
Sam S Ochi is a prominent inventor based in San Jose, California. He has made significant contributions to the field of electronics, particularly in the development of advanced switching circuits. With a total of eight patents to his name, Ochi's work has had a lasting impact on the industry.
Latest Patents
Among his latest patents is the JFET switch circuit, which combines JFET and bipolar transistor devices into an analog signal switching circuit. This innovative design allows a JFET to act as a switch device for controlling analog signals. The JFET gate is charged through a bipolar transistor to turn it off and discharged through a second bipolar transistor to turn it on. A second JFET is utilized to control the conduction of the second bipolar transistor, ensuring it only conducts heavily when a high slew rate is required. This circuit can switch analog signals rapidly while maintaining very low quiescent current drain in both off and on states. Additionally, Ochi has developed a JFET base junction transistor clamp, which prevents a base junction transistor inverter circuit from entering saturation. This is achieved by diverting the drive current through a p-channel field effect transistor connected between the base and collector of the junction transistor.
