description The invention discloses a low distortion factor oscillator system. The low distortion factor oscillator system is characterized by comprising a signal amplification circuit, a positive feedback circuit connected with the signal amplification circuit, a frequency selecting circuit connected with the positive feedback circuit, and a buffer circuit connected with the frequency selecting circuit, wherein the buffer circuit comprises a transformer T, a bigrid field-effect tube Q2, a capacitor C3, a resistor R10, a resistor R11, a resistor R8, and a resistor R9, wherein the anode of the capacitor C3 is connected with the a grid of the bigrid field-effect tube Q2, the cathode of the capacitor C3 is grounded, the resistor R10 and the capacitor C3 are in parallel connection, one end of the resistor R11 is connected with the anode of the capacitor C3, the other end of the resistor R11 is connected with a resistor R12 and then is connected with an end of the same name of the primary side of the transformer T, one end of the resistor R8 is connected with the b grid of the bigrid field-effect tube Q2, the other end of the resistor R8 is connected with the capacitor C2 and then is connected with the source electrode of the bigrid field-effect tube Q2, one end of the resistor R9 is connected with the source electrode of the bigrid field-effect tube Q2, and the other end of the resistor R9 is connected with connecting points of the resistor R8 and the capacitor C2. The low distortion factor oscillator system can effectively prevent load effect in the system and frequency shift caused by load change, thereby realizing low distortion factor of an oscillating circuit.
