Latest Patents

Dongxue Dai holds a patent for a method titled "Method for achieving terminal-pair definition of four-terminal-pair impedance and application thereof." This invention provides a novel approach to defining terminal pairs in four-terminal-pair (4TP) impedance. The method involves connecting a current output terminal of a two-stage follower to a high current terminal of impedance through a coaxial line. Additionally, it connects a voltage output terminal of the two-stage follower to a high voltage terminal of the impedance, ensuring that the current of the high voltage terminal is zero. This innovative design allows for equal and reverse currents in the core wire and outer wire of the high current terminal. The invention significantly improves the balancing speed of the 4TP impedance bridge, enabling accurate and fast comparative measurements with high precision.
