| Abstract: | The paper presents the engineering background of capacitor tap in high frequency circuit, and discussesthe actual effect of source and load on the LC tank, as well as the practical value of partial access method to solve theproblem. Based on the elementary circuit theory and impedance transformation formula, equivalent calculation ofcapacitor tap is carried out respectively. The paper puts forward the error problem, and illustrates the reason bymeans of analysis. Finally, Software multisim is used to test the design circuit, and simulating results demonstrate theaccuracy of the theory analysis and calculation. |
