Understand inductors and their applications

Inductance, also known as inductance coil, is an electromagnetic induction element wound by insulated wire (such as enameled wire, gauze wire, etc.), which is one of the components commonly used in electronic circuits. Inductor is a series of coaxial line turns made of enamel wire, gauze wire or plastic leather wire wound on the insulating…

Common-mode inductor

Common-mode inductor

Working principle of common mode inductor Common mode inductance In a circuit, when a differential mode signal passes through a common mode inductor, the magnetic flux produced by the differential mode signal in the core is equal in magnitude and opposite in direction. The net flux is zero, so the common-mode inductance to the differential…

Integrated operational amplifier

Integrated operational amplifier

Of 1. (1) The input stage is composed of a differential amplifier circuit to improve the input resistance, reduce the zero drift, and obtain a higher CMRR. (2) The intermediate amplifier stage is composed of multiple directly coupled voltage amplifiers to obtain higher voltage amplification. (3) The output stage is composed of emitter output device…
