一些与Q因素和策略相关的考虑

随着Q值的提高,调谐电路滤波器的带宽会降低。当损耗开始减少时,调谐电路中的锐度也随着能量以更好的方式存储在电路中而降低。很明显,当Q开始增加时,带宽开始减少,整个调谐电路响应也增加。

当q区的谐振电路增强时,损耗会同时减少。这就意味着,电路中任何的振荡都需要更多的时间才能消失。简而言之,电路将有响铃增多的趋势(Hausmann et al., 2013)。这实际上是一个理想的利用在电路的振荡器,因为它很容易设置和维持振荡,较少的能量损失在电路调谐。

所有谐振器一般都会产生相位噪声,包括信号相位内的随机移位。这是为了显示噪声从关键载波扩散。这样的噪音是不需要的,因此需要最小化。振荡器的设计可以通过各种方式来减少这种影响。提高振荡器调谐电路的Q系数是解决这一问题的关键。

进一步提出了Q因子公式,表明小腔内的损耗可以得到一个好的Q值,大的L值。然而,这些术语并不具有独立性,因为积累性质的传播随着空腔的长度而增强(Matere et al., 2016)。为了提高谐振腔的q系数,减小谐振腔的损耗是很重要的。通过较高的SOI材料质量和较高的加工质量,可以减少传播损失。弯道中的损失可以通过绝热设计弯道来减少,这种弯道以更平滑的方式弯曲而不是以圆形方式弯曲。

Some considerations related to Q factor and Finesse

With enhancing Q, the tuned circuit filter bandwidth is decreased. As loss starts decreasing, the sharpness in the tuning circuit also decreases as energy gets stored in a better manner within the circuit. It can be evident that as the Q starts increasing, the bandwidth starts decreasing and the complete tuned circuit response increases as well.

As the resonant circuit in the q enhances, there occurs a simultaneous decrease in the loss. This implies that any set up of oscillation across the circuit takes more time for dying away. In brief, circuit will have a tendency of ringing more (Hausmann et al., 2013). This actually is ideal for utilization within the circuit of oscillator as it is easy for setting up and maintaining oscillations with lesser energy being lost within the circuit tuning.

All resonators generally generate phase noises comprising randomized shifts within the signal phase. This is responsible for manifesting the noise spreading from the key carrier. Such a noise is not needed and henceforth requires minimization. The design of the oscillator can get tailored for reducing this in various manners. The key perspective from this lies in increasing the oscillator tuned circuit Q factor.

The Q-factor formula further is of the suggestion that a good Q has been gained for loss in small cavity and large L is gained. However such terms do not have independence as the propagation of accumulated nature enhanced with the length of the cavity (Matere et al., 2016). In order to enhance the Q-factor, it is important to decrease the cavity losses. Losses of propagation are diminished through higher SOI material quality and higher processing quality. Losses in the bend might get decreased through adiabatic design bends which curve in a smoother manner rather than bending in a circular manner.
