2021年2月20日 · 在 VCO 处于控制环路中的应用中,如 PLL,调谐灵敏度是 VCO 元件的增益,可能会影响控制环路的动态性能和稳定性。 VCO 的输出功率规定了向指定阻抗负载输送的功率,对于 RF VCO 来说通常是 50 欧姆 (Ω)。
PLL,VCO技术经验总结 - RFIC/射频电路 - RF技术社区
2010年3月3日 · VCO是频率合成器中的重要器件,其输出频率受电压控制,可以做成很宽的调谐范围,制作出宽带跳频的频率源。 VCO主要考核指标包括中心频率、调谐范围、压控振荡器的增益、调谐线性度、相位噪声、输出信号频谱纯度(杂散和谐波)、输出电压幅值等。 在设计 VCO 时,VCO振荡回路中三极管/场效应管的静态和动态工作特性非常重要,VCO的噪声基本上都是牵制于三极管,而另一部分噪声就受制于电源,但是这部分较三极管本身特性容易控制。 其次就 …
