Circuit's Functions If the transistor's collector load adopts LC resonance loop and the oscillation frequency of Pierce C - B or Boer, B - E circuit must attuned a little deflective to make the oscillation stable.This oscillating circuit can be used if there is no inductance L. Circuit's Work Principle If quartz resonator is used as inductance L,it can be used as deformation carat diop oscillating circuit.Capacitor C2 and C3 feedback posistively and the frequency is low and electric capacity is large. The oscillation frequency reaches 5~20MHZ when capacity is 100PF and a proper capacity can be chosen according to requirements.
