  • The performances of RF(radio frequency) integrated circuit(RFIC) spiral inductors on silicon(SIOS) with different planar structures were simulated based on a typical physical model using the HFSS(high frequency structure simulator).The simulated results are well coincident with those from theoretical analysis.Compared with those of the quadrilateral and octagonal ones with the same inner radius,the maximum quality factor Q of the circular spiral inductor increases by 0.90 and 0.80 times,respectively;at the frequency corresponding to the maximum quality factor the reflection coefficient of the circular spiral inductor decreases by about 32.5% and 26.6%,respectively,and the masses of metals used decrease by about 30% and 20%,respectively;and the band width of the circular spiral inductor is about 60% and 30% wider,respectively,for Q5.
