单一电阻控制的振荡器,除了用作频率可变的正弦波发生器外,还可用作压控振荡器(用场效应晶体管作压变电阻来代替控制频率的电阻),并且配以适当的转换器用于一些测量系统。过去几年,有些文献已叙述了大量这样的振荡器。然而,从实现电路集成的观点来看,振荡器使用接地电容器更为有利(对单片和混合集成电路结构都是这样)。近来,Sunda-ramurthy等叙述了这样的振荡器,使用三个运算放大器。
A single, resistor-controlled oscillator, in addition to its use as a variable frequency sine wave generator, can also be used as a voltage-controlled oscillator (a field-effect transistor is used as a resistor instead of a control frequency) with a suitable The converter is used in some measurement systems. In the past few years, a large number of such oscillators have been described in some documents. However, it is more advantageous for the oscillator to use a grounded capacitor from the point of view of circuit integration (both monolithic and hybrid integrated circuit structures). Recently, Sunda-ramurthy et al. Described such oscillators using three operational amplifiers.
