摘要
通过分析测量BJT的S参数与稳定因子K,并利用已测量的BJT输出阻抗ZOUT来设计输出匹配电路,使整体电路在2.4 GHz的频率上产生振荡。利用ADS软件对电路进行仿真,达到在BJT特定的偏压下,仍在2.4 GHz的频率上持续振荡,并可利用电压的变化来控制其振荡频率的目的。
By analyzing and measuring the S-parameter and stability factor K of BJT, the BJT output impedance ZOUT measured previously was used to design the matching output circuit to make the overall circuit generate oscillations in 2.4 GHz. Using the ADS to simulate the circuit, the oscillation generated can be sustained in the frequency of 2.4 GHz under a specific bias of BJT and the voltage change can be used to control the oscillation frequency.
