LC sine-wave oscillators using generalpurpose voltage operational-amplifiers

摘要

It has been found that some textbooks on basic electronics show LC oscillators that may not work as assumed. According to the results in this paper, such a difficulty stems from the fact that LC oscillators are normally designed to work with transconductance- not with voltage-amplifiers. This problem, however, can be readily solved by connecting a resistor in series with the so-called frequency-determining network.
