振荡器谐振幅度 VCO 压控振荡器 指标 LC-VCO 的调节 LC 振荡器的振荡频率等于fosc=1/(2πLC),因为改变单片电感的值很困难,我们可以调节电容值来调节振荡器。电容值与电压值有关的电容被称为“可变电容器” (varactor)。 如上图所示,变容二极管可以使用 MOS 管构成。 VCO 的数学模型 LC-VCO 的设计 电路结...
Since January 2001, he has been with M/A-COM Eurotec as a principal engineer, where he is involved in the design and development of the handset advanced transmitter architectures in general and in GaP/GaAs HBT power amplifier modules for new generations of wireless communicat...
Now consider a varactor-controlled oscillator with the varactor as a nonlinear element whose capacitance depends not only on the applied DC bias voltage but also on the amplitude of the self-sustained oscillations. The basic VCO circuit consists of the varactor with a nonlinear...
