More Information
Summary:A kind of composite admittance device consists of a first admittance element and special active admittance components. In the above mentioned active admittance components, there are a second admittance element which has better performance under prescribed condition, a third admittance element whose impedance type is same as and its normal value is equal to those of the first admittance element, and an active amplifying circuit. The stability and accuracy or quality factor (i.e. the orthogonal component) of such made composite admittance device are very good, and it not only can meet the rquirement for checking various digital impedance measurers, but also can produce, by such method, the high-property capacitors, inductors and resistors used in various circuits.
