Problems solved by technology

[0002] When measuring the inductor current in a DC circuit, it is the fastest method to directly connect the inductor with a wire to measure the current in the inductor. However, because the wire itself has a certain resistance value, it will cause a large error in the measurement.

Abstract

Provided is an inductor of an integrated RC circuit. The inductor comprises an inductor portion, a resistor, and a capacitor. The resistor and the capacitor are connected in series to form the RC circuit. The first end of the inductor portion is connected with the second end of the inductor portion successively through the resistor and the capacitor. The first end of the inductor portion and the resistor are connected via a first contact. The resistor and the capacitor are connected via a second contact. The capacitor and the second end of the inductor portion are connected via a third contact. The first contact to the third contact are arranged on the surface layer of the inductor. By means of the above design, when the current of the inductor is measured, the voltage on the two ends of the capacitor can be directly measured and the current of the inductor is obtained by calculation while the circuit is not required to be reconstructed.

Description

technical field [0001] The invention relates to an inductance, in particular to an inductance of an integrated RC circuit. Background technique [0002] When measuring the inductor current in a DC circuit, it is the fastest method to directly connect the inductor with a wire to measure the current in the inductor. However, because the wire itself has a certain resistance value, it will cause a large error in the measurement. Contents of the invention [0003] In view of this, it is necessary to provide an inductance of an integrated RC circuit that improves the accuracy of inductance current testing. [0004] An inductor integrating an RC circuit comprising: [0005] an inductance part; [0006] A resistor and a capacitor, the resistor and the capacitor are connected in series to form an RC circuit, wherein the resistance of the resistor is R1, the capacitance of the capacitor is C1, the inductance of the inductance part is L1 and the inductance The equivalent series re...
