关于并联晶体振荡器的振荡频率,在各种教材中,看法不尽相同。大多认为,并联晶体振荡器的振荡频率在石英谐振器的并联谐振频率附近;少数认为是在石英谐振器的串联谐振频率附近,本文将证明后一种说法是正确的。图1是石英谐振器的等效电路,在不考虑晶体的损耗时,它的串联谐振频率为 About the oscillation frequency of the parallel crystal oscillator, in a variety of textbooks, the views vary. Most believe that the parallel crystal oscillator oscillation frequency near the parallel resonant frequency of the quartz resonator; a few believe that the quartz resonator in the vicinity of the series resonant frequency, the paper will prove that the latter is correct. Figure 1 is the equivalent circuit of quartz resonator, without considering the loss of the crystal, its series resonant frequency
