摘要： A method and a device for estimating parameter variations of transistors that belong to the same circuit. The method includes: providing the first circuit; providing a test circuit adapted to perform a first function and a stacked test circuit adapted to perform a second function that substantially equals the first function; wherein the test circuit, the stacked test circuit and the first circuit are processed under substantially the same processing conditions; determining a relationship between a parameter of the test circuit and a parameter of the stacked test circuit; and estimating parameter variations of transistors that belong to the first circuit in response to the determined relationship.

摘要： An electric energy meter comprises a terminal unit and a measurement unit. The terminal unit includes plural electric lines each of which carries an electric current supplied from an external power source to a load, and a coil which is provided to at least one of the plural electric lines and converts the electric current flowing to the load into a magnetic field directly proportional to the electric current. The measurement unit includes a hall element which generates a voltage directly proportional to the magnetic field converted by the coil, a voltage detector which detects voltages of the plural electric lines, and a processing unit which calculates electric energy consumption based on the voltage generated by the hall element and the voltages detected by the voltage detector. The electric energy meter can facilitate the replacement.

摘要： Non-magnetic metallic spacers are welded into the auxiliary air gaps of a voltage stator using welding passes arranged in a predetermined sequence. The presence of the spacers stabilizes the auxiliary air gap against change in light load adjustment. Sequences of welding passes are disclosed effective for holding inherent light load error at nominal values, or biasing it positively or negatively.
