变容二极管调谐，变容管调谐

A switched varactor array is proposed to suppress tuning gain fluctuation for the performance of the phase locked loop ( PLL).
该振荡器包含了一个开关可变电容阵列，用以抑制调谐增益的变化。
Especially, with the decrease of the thickness of the gate oxide, an irregular change of the varactor's tuning range is observed, which is due to the gate depletion of polysilicon.
在模拟中，还观察到了当栅氧厚度很薄时，多晶硅栅耗尽导致的可调电容的变化范围不规则变化的现象。
A varactor is used to tune the frequency of the VCO, and optimization is processed to get broad tuning band.
VCO采用变容二极管进行并联电调谐，并优化电路以获取较宽的调谐频带。
The output powers of the fundament signal and the second harmonic signal are low. The varactor diode does not implement electric tuning effectively. Further study should be carried out.
两路信号的输出功率较低，变容管没能有效的实现电调谐的功能，有待进一步地研究。
Because the wideband voltage-controlled oscillator which using the varactor diode as a tuning device has the advantage of small size, low cost, flexible design, it represent a significant proportion at wideband voltage-controlled oscillators.
以变容二极管作为调谐器件的表贴型宽带压控振荡器因体积小、成本低、设计灵活等优点，在宽带压控振荡器中占有很大比例。
