فرکانس نوسان رله زمانی دستگاه بسته بندی تاول

Oscillation frequency f and RC have the following approximate relationship f=1/2.2Rt?Cr (Vdd=10V). For example, considering the stability of the oscillator, reduce the variation of the oscillation period caused by the difference of device parameters Rs>Rt (when Rs=10Rt, the oscillation period basically does not change with the change of Vdd) to ensure that the oscillation can start up reliably. When choosing Rt and Ct, attention should be paid to their conditions, Rt>1KΩ?Cr>1000Pf، در غیر این صورت اطمینان از راه اندازی قابل اعتماد مدار اسیلاتور دشوار است.
