Latest Patents

Xia Liu 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 solution for achieving terminal-pair definition of 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, a voltage output terminal of the two-stage follower is connected to a high voltage terminal of the impedance through the same coaxial line. This configuration ensures that the current of the high voltage terminal is zero, allowing core wire currents and outer wire currents of the high current terminal to be equal and reverse. The invention accelerates the balancing speed of the 4TP impedance bridge, enabling accurate and fast comparative measurements with high precision of the 4TP AC impedance.
