本例提出了一个新颖的振荡器结构。它使用一个串联LC(电感-电容)储能电路,使调谐范围大于采用并联LC方式的电路。这种振荡器结构能够获得宽的频率区间,明显超过最好的宽带调谐变容二极管性能。工程师们都认为现有水平的VCO(压控振荡器)能够覆盖一个倍频程。这种结构可实现4:1的输出频率。只用LC储能电路就能设定这个频率,因此其它元件的寄生电容不会限制输出频率。与标准振荡 This example presents a novel oscillator structure. It uses a series LC (inductive-capacitive) tank circuit to make the tuning range greater than with parallel LC mode circuits. This oscillator architecture enables a wide range of frequencies to be achieved, significantly outperforming the best broadband tuned varactor performance. Engineers agree that existing levels of VCOs (voltage-controlled oscillators) can cover an octave. This structure achieves a 4: 1 output frequency. Only the LC tank circuit can set this frequency, so the parasitic capacitance of other components does not limit the output frequency. With standard oscillation
