Oscillation zaus ntawm lub sij hawm relay ntawm blister ntim tshuab

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, txwv tsis pub nws yog ib qho nyuaj los xyuas kom meej qhov pib txhim khu kev qha ntawm lub oscillator circuit.
