ABSTRACT:
A damping circuit includes two circuits. Each circuit has a PNP transistor, an NPN transistor, and a shunt resistor. The PNP transistors are connected in series to the NPN transistors through level shift stages. The PNP transistor and the NPN transistor have emitter functions of the same area. The shunt resistors are connected to the emitters of the NPN transistors. Both of the two circuits are connected to a coil in parallel in such a manner that the two circuits have opposite polarities to each other about the coil.
