Filed: 1980-05-22
Abstract: PURPOSE:To reduce the inductance value of a coil and the capacitance of a capacitor, by making the Norton's conversion in the setting of a ladder type circuit at least in one of two two-terminal circuits. CONSTITUTION:In chained lines A-A', the Norton's conversion is made by resistors R3 and R4. Hereupon, the equivalent circuit of a circuit including an ideal transformer as shown in fig. (2) is shown in the circuit in fig. (3) and equation I is satisfied. In equation I, if n<1, the R takes a negative value. Thus, by selecting the winding ratio(n) of the ideal transformer so that ¦R¦=n<2>R4 is satisfied, the resistors are cancelled with each other to obtain the circuit as shown in fig. (4) and equation II is established. Thus, as known from the equation of (n) in equation II, the inductance value of a coil can be reduced through the conversion.
