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)。 image-20210328213837766 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 ...
This paper describes the design of a new 8-path pseudo switched-capacitor LC bandpass filter and its command circuit made up by a ring voltage controlled oscillator (VCO) with ‘XOR’ gates. The proposed architecture presents the possibility of tuning over a frequency broadband allowing to sweep...
