Title: Innovations of Ronald W. Russell
Introduction
Ronald W. Russell is a prominent inventor based in Sunnyvale, California. He has made significant contributions to the field of integrated circuits, holding a total of nine patents. His work focuses on enhancing the functionality and reliability of electronic devices.
Latest Patents
One of Ronald's latest patents is titled "User-proof post-assembly offset voltage trim." This invention outlines a method for setting a post-assembly trim of a monolithic integrated circuit (IC) using selected package pins to address the on-chip trim circuit. After the trim is completed, the circuit ensures that the trim pins are disconnected from the trim circuit, making the IC user-proof. This innovation is particularly beneficial for plastic encapsulated devices, and it also discusses the use of zener zapping and fuse blowing for cavity-containing packages.
Another notable patent is "Operational amplifier offset trim that does not change the offset." This patent describes a JFET operational amplifier input stage along with an offset potential trimming circuit. The trimming circuit features a scaled-down compensation stage that operates independently of temperature, generating a trimming current that inversely varies with the transconductance of the input stage. This allows for compensation of the input offset potential without altering the temperature drift, achieving effective results after device assembly.
