| 摘 要： | 本文首次研制了一种基于双基区晶体管(DUBAT)的无电感新型压控振荡器(VCO).文中详细分析了其工作原理,并给出了它的等效电路,模拟结果与实验结果是一致的.由于DUBAT结构简单,工艺与双极集成电路工艺完全相容,从而为压控振荡器结合其它功能电路的大规模集成提供了一种新的实现方式.

| Abstract: | A novel Voltage Controlled Oscillator (VCO) without inductances has been fabricated for the first time based on Dual Base Transistor (DUBAT).The operating mechanism is analyzed in detail and the equivalent circuit is proposed.The results simulated by SPICE are consistent with those of experiments.The features of the simplicity of DUBAT structure and the compatibility of bipolar integrating process make this novel VCO a promising candidate for combination of VCO with functional circuits on a single silicon chip. |
