【摘要】 薄膜变压器射频集成电路的一种关键器件。该文设计了一种层叠型螺旋薄膜变压器,并分别用MATLAB和Agilent ADS对薄膜变压器进行了S参数仿真。仿真结果表明,匝数N=15时,在160-240MHz频率范围之间,取得最高传输效率为98%。通过软件仿真研究了不同匝数比对薄膜变压器性能的影响,分析了产生这种影响的因素。更多还原

【Abstract】 On-chip transformers are highly required in RFIC circuits.A stacked on-chip transformer was designed.S-parameter is simulated by both MATLAB and Agilent ADS software.The results show that the maximum transmission efficiency of the transformer with 15 turns is 98% at 160MHz-240MHz.Different turns of on-chip transformers influenced the performance of on-chip transformer was analyzed.更多还原
