幅度稳定度和频率稳定度是设计振荡器的主要问题。后者一般是涉及选择适当的元件,而前者是这里设计的放大器要解决的。若振幅稳定度和失真要求不高,简单的限幅型振荡器一般就足够了。获得幅度稳定的一种方法是加入诸如自 Amplitude stability and frequency stability are the major issues in designing oscillators. The latter typically involves selecting the appropriate component, the former being the amplifier designed here to be solved. If the amplitude stability and distortion requirements are not high, a simple limiter oscillator is generally sufficient. One way to gain stability is to add something like self
