Design And Modeling Of Small Solenoid Inductor For Radio Frequency Circuits

Design and modeling of solenoid inductor is presented. The effect of thickness of magnetic cores, number of turns, width of magnetic cores and width of coils of solenoid inductor on inductance, quality factor and Self-resonant frequency are considered. Development in percentage increase of quality factor is due to increase in width of magnetic cores. It can be found that ~32% of solenoid area reduction is observed when compared with conventional solenoid inductor design. The effective inductance and quality factor is checked by simulation for dynamic variation of various parameters over the desired frequency range. The dimension of solenoid inductor considered for asnalysis is 100 μm ×100 μm, suitable for better solenoid inductor design in high frequency radio frequency circuits.
