| 摘 要： | 在皮尔斯陶瓷晶振电路的发射极串接一个适量的电感使晶体管的c-e间和b-e间都成为一个串联谐振电路,其谐振频率稍高于陶瓷晶振频率,从而提高了其容抗对频率变化斜率,进一步提高了整个电路的频率稳定性。

| Abstract: | A suitable inductor which is put in series with emitter circuit of the pierce crystal osillator circuit makes the b-e branch and c-e branch of transistor both to become series resonat circuits, which have resonat frequencies bighter than that of ceramic oscillator. Thereby, frequency change slope of condenive reactance is increased, frequency stability of whole circuit is furthermore improved. |
